Command line options

This page summarizes command line options for the Shasta executable. We will make an effort to keep this page consistent with the code, but discrepancies may temporarily appear as we add new features. In that case, the list of command line options obtained by invoking the Shasta executable with --help is more authoritative than the contents of this page.

Saving some typing

Many option names are long and descriptive. To make it easier to type them Shasta provides the ability to create a bash completion script. If you are using the bash shell (the default shell in most modern Linux distributions), you can use the commands below to save yourself some typing. This assumes that the shasta executable is named just like this - shasta - and is accessible via your PATH environment variable (if it is not, you have to invoke shasta using an absolute or relative path):

shasta --command createBashCompletionScript
source shastaCompletion.sh
The first command creates a script named shastaCompletion.sh. The second command runs that script in the current shell (this is important - running the script without the source command will not work). Now, while typing a shasta option or keyword, you can press TAB, and the option name will be completed as much as can be done without ambiguity. You can also press TAB a second time to get suggestions for what could be allowed next.

The command that generates the script can be run only once, but you will need to rerun the source command above every time you start a new shell. Alternatively, you can put the source command in your .bashrc file or in one of the standard locations used to store bash completion scripts.

Options allowed only on the command line

OptionDefault
value
Description
--help or -h Use this option to obtain a summary of allowed command line options.
--version or -v Identify the Shasta version.
--config Specifies the name of a pre-built configuration or a configuration file. This option has no default and is mandatory when running an assembly.
--input Specifies the names of the input files for the assembly. This option is mandatory. At least one input file must be specified. To specify multiple input files, enter them separated by space after --input.
--anchors Specifies the names of the json files containing anchor definitions for mode 3 assembly. To specify multiple input files, enter them separated by space after --anchors.
--assemblyDirectoryShastaRun Specifies the name of the directory where assembly output is stored. If --command is assemble (the default), this directory must not exist and is automatically created. For most other commands, this directory must exist. See here for more information on the output files created by Shasta.
--commandassemble Specifies the Shasta command to be run.
--memoryMode
(not supported on MacOS)
anonymous
  • Can be anonymous or filesystem.
  • For best performance use --memoryMode filesystem --memoryBacking 2M. However, using these options require root access via sudo. Depending on sudo setup, this may result in prompting for a password.
  • Not supported on MacOS. On MacOS, Shasta operates as if --memoryMode filesystem --memoryBacking disk was specified.
--memoryBacking
(not supported on MacOS)
4K
  • Can be disk, 4K, or 2M.
  • For best performance use --memoryMode filesystem --memoryBacking 2M. However, using these options requires root access via sudo. Depending on sudo setup, this may result in prompting for a password.
  • Not supported on MacOS. On MacOS, Shasta operates as if --memoryMode filesystem --memoryBacking disk was specified.
--threads0 Specifies the number of threads to be used, or 0 to request one thread per virtual processor.
--suppressStdoutLogfalse This is a Boolean switch. Normally, Shasta duplicates output to stdout by sending a copy to stdout.log in the assembly directory. If this option is used, this behavior is suppressed, and stdout.log is not created.
--exploreAccessuser Specifies access control for --command explore.
--port17100 The TCP port to be used for --command explore. If the specified port is not available, Shasta will try again after incrementing the port number a few times.
--alignmentsPafFile"" The name of a PAF file containing alignments of reads to a reference. Only used for --command explore, for display of the alignment candidate graph. Experimental.

Options allowed on the command line and in a configuration file

See here for the format required to enter these options in a configuration file.

OptionDefault
value
Description
--Reads.representation1 Read representation: 0 = raw sequence, 1 = Run-Length Encoded (RLE) sequence. Experimental. Do not use.
--Reads.minReadLength10000 Read length cutoff. Reads shorter than this number of bases are discarded on input and not used in the assembly.
--Reads.desiredCoverage0 Specifies a desired value for total coverage, in bases. If not zero, the read length cutoff specified via --Reads.minReadLength is increased to reduce coverage to the specified value. This value can be specified as a number of bases, or using power of 10 multipliers immediately following the numeric value. The powers of ten can be abbreviated as G, Gb, or Gbp for 109 bases, M, Mb, or Mbp for 106 bases, K, Kb, or Kbp for 103 bases. For example, a desired coverage of 120×109 bases can be requested specifying 120G, 120Gb, 120Gbp, or 120000000000. If coverage available using only reads longer than Reads.minReadLength is less than the value specified for --Reads.desiredCoverage, the assembly terminates with an error message.
--Reads.noCacheFalse This is a Boolean switch. If set, requests skipping the Linux cache when loading reads. Implemented for Linux only (uses the O_DIRECT flag). Can help performance, but only use it if you know you will not need to access the input files again soon.
--Reads.handleDuplicatesuseOneCopy Specifies how to handle reads with duplicate names (the name of a read is its id in an input fasta or fastq file). These can occasionally occur, typically due to glitches in the basecalling or subsequent pipelines before assembly starts. Can be one of the following:
  • useAllCopies: All copies of reads with duplicate names are used in the assembly. This can cause artifacts in some cases. This was the Shasta behavior before this option was introduced.
  • useOneCopy: For each set of reads with duplicate names, only one read is used in the assembly. This is the default.
  • useNone: None of the reads with duplicate names are used in the assembly.
  • forbid: If any reads with duplicate names are found, the assembly stops.
In all cases, a message is written with the number of reads with duplicate names found, and the number of reads that were discarded for that reason. A file DuplicateReads.csv , listing details for all reads wth duplicate names, is also written to the assembly directory.
--Reads.palindromicReads.skipFlaggingFalse Skip flagging palindromic reads. Oxford Nanopore reads should be flagged for better results.
--Reads.palindromicReads.maxSkip100 Same as Align.maxSkip but applied only to self reverse-complement alignments for the purpose of detecting palindromes.
--Reads.palindromicReads.maxMarkerFrequency10 Same as Align.maxMarkerFrequency but applied only to self reverse-complement alignments for the purpose of detecting palindromes.
--Reads.palindromicReads.alignedFractionThreshold0.1 Same as Align.maxMarkerFrequency but applied only to self reverse-complement alignments for the purpose of detecting palindromes.
--Reads.palindromicReads.nearDiagonalFractionThreshold0.1 Count the fraction of markers within deltaThreshold (distance in markers) from the diagonal and only flag reads above this fraction as palindromic.
--Reads.palindromicReads.deltaThreshold100 Used in combination with nearDiagonalFraction. This value defines how far from the diagonal markers must be to be counted towards the nearDiagonalFraction. Unit is in markers.
--Kmers.generationMethod0 Used to select how k-mers to be used as markers are generated. Can be one of the following:
  • 0: Random selection.
  • 1: Random selection, excluding k-mers that are globally overenriched, as defined by their global frequency in input reads, and by the value specified as --Kmers.enrichmentThreshold. Only supported when --Kmers.k is less than 16.
  • 2: Random selection, excluding k-mers that are overenriched even in a single read, as defined by the value specified as --Kmers.enrichmentThreshold. Only supported when --Kmers.k is less than 16.
  • 3: Read from file. Use --Kmers.file to specify the file. Only supported when --Kmers.k is less than 16.
  • 4: Random selection, excluding k-mers that appear in two copies close to each other, even in a single read. The two k-mer copies are considered close if they occur at a distance from each other less than --Kmers.distanceThreshold RLE bases. Only supported when --Kmers.k is less than 16.
--Kmers.k10 Length of marker k-mers (in run-length representation). Can be up to 31 for Mode 0 assembly, 30 for Mode 2 assembly.
--Kmers.probability0.1 Probability that a k-mer is selected to be used as a marker.
--Kmers.enrichmentThreshold100. This controls the enrichment threshold above which k-mers are considered overenriched. Enrichment is ratio of k-mer frequency in reads to random. Only used if --Kmers.generationMethod is 1 or 2.
--Kmers.distanceThreshold1000 Distance threshold, in RLE bases, for --Kmers.generationMethod 4. Only used if --Kmers.generationMethod is 4.
--Kmers.file The absolute path of a file containing the k-mers to be used as markers, one per line. Only used if --Kmers.generationMethod is 3.
--MinHash.version0 The version of the MinHash/LowHash algorithm to be used. Must be 0 (default).
--MinHash.m4 The number of consecutive markers that define a MinHash/LowHash feature.
--MinHash.hashFraction0.01 Defines how low a hash has to be to be used with the LowHash algorithm.
--MinHash.minHashIterationCount10 The number of MinHash/LowHash iterations, or 0 to let --MinHash.alignmentCandidatesPerRead control the number of iterations.
--MinHash.alignmentCandidatesPerRead20 If --MinHash.minHashIterationCount is 0, MinHash iteration is stopped when the average number of alignment candidates that each read is involved in reaches this value. If --MinHash.minHashIterationCount is not 0, this is not used.
--MinHash.minBucketSize0 The minimum size for a bucket to be used by the MinHash/LowHash algoritm. If minBucketSize and maxBucketSize are both 0, they are adjusted automatically at each iteration using simple heuristics.
--MinHash.maxBucketSize10 The maximum size for a bucket to be used by the MinHash/LowHash algoritm. If minBucketSize and maxBucketSize are both 0, they are adjusted automatically at each iteration using simple heuristics.
--MinHash.minFrequency2 The minimum number of times a pair of reads must be found by the MinHash/LowHash algorithm in order to be considered a candidate alignment.
--MinHash.allPairsFalse This is a Boolean switch that causes the MinHash process to be skipped. Instead, all possible read pairs are marked as alignment candidates, on both relative orientations. This should only be used for very small test assemblies as it can become prohibitively slow for large assemblies.
--Align.alignMethod3 The alignment method to be used to compute marker alignments between reads:
  • 0 = Old Shasta alignment method. Use this to reproduce Shasta behavior before release 0.5.0.
  • 1 = SeqAn. This gives the best alignment results but it is slow and should only be used for testing.
  • 3 = Banded SeqAn.
  • 4 and 5 = experimental.

--Align.bandExtend10 Amount to extend the alignment band, in markers (only used for alignment method 3).
--Align.maxBand1000 Maximum band width, in markers, for banded marker alignments (only used for alignment method 3).
--Align.sameChannelReadAlignment.suppressDeltaThreshold0 If not zero, alignments between reads from the same nanopore channel and close in time are suppressed. The read meta data fields from the FASTA or FASTQ header are checked. If their difference, in absolute value, is less than the value of this option, the alignment is suppressed. This can help avoid assembly artifact. This check is only done if the two reads have identical metadata fields runid, sampleid, and ch. If any of these metadata fields are missing, this check is suppressed and this option has no effect.
--Align.suppressContainmentsFalse This is a Boolean switch. If set, containment alignments are suppressed. Containment alignments are alignments in which one read is entirely contained in another read, except possibly for up to maxTrim markers at the beginning and end.
--Align.align4.deltaX200 Only used for alignment method 4 (experimental).

  • 0 = No strand separation.
  • 1 = Limited strand separation (default).
  • 2 = Strict strand separation.

--MarkerGraph.maxCoverage100 The maximum coverage for a marker graph vertex. Vertices with higher coverage are not generated.
--MarkerGraph.minCoveragePerStrand0 The minimum coverage per strand for a marker graph vertex. Vertices with lower coverage on either strand are not generated.

--MarkerGraph.duplicateMarkersPattern1Threshold0.5 Used when cleaning up marker graph vertices with more than one marker on the same oriented read. Experimental.
--MarkerGraph.lowCoverageThreshold0 Used during approximate transitive reduction. Edges with coverage less than or equal to this value are unconditionally removed from the marker graph, even at the cost of breaking reachability. This never happens with the default value 0.
--MarkerGraph.highCoverageThreshold256 Used during approximate transitive reduction. Edges with coverage greater than or equal to this value are unconditionally kept in the marker graph, even if they could be removed without breaking reachability. This never happens with the default value 256, because marker graph edge coverage is stored in one byte and saturates at 255.
--MarkerGraph.maxDistance30 Used during approximate transitive reduction of the marker graph. It controls the length of each Breadth First Search (BFS) used to determine reachability. This length is expressed in marker graph edges.
--MarkerGraph.edgeMarkerSkipThreshold100 Used during approximate transitive reduction of the marker graph. Edges with coverage 1 are unconditionally removed from the marker graph if the only supporting read has a marker skip of more than this number of markers on that edge. Large marker skips are indicative of artifacts or errors.
--MarkerGraph.pruneIterationCount6 The number of marker graph prune iterations. This equals the maximum length of dead branches that are removed.
--MarkerGraph.simplifyMaxLength10,100,1000 Used for bubble removal.
--MarkerGraph.crossEdgeCoverageThreshold0. Experimental. Cross edge coverage threshold. If this is not zero, assembly graph cross-edges with average edge coverage less than this value are removed, together with the corresponding marker graph edges. A cross edge is defined as an edge v0->v1 with out-degree(v0)>1, in-degree(v1)>1.
--MarkerGraph.peakFinder.minAreaFraction0.08 Used in the automatic selection of --MarkerGraph.minCoverage when --MarkerGraph.minCoverage is set to 0.
