Allowed values: anonymous, filesystem. --memoryBacking arg (=4K) Specify the type of pages used to back memory. Allowed values: disk, 4K , 2M (for best performance). All combinations (memoryMode, memoryBacking) are allowed except for (anonymous, disk). Some combinations require root privilege, which is obtained using sudo and may result in a password prompting depending on your sudo set up. --threads arg (=0) Number of threads, or 0 to use one thread per virtual processor. --exploreAccess arg (=user) Specify allowed access for --command explore. Allowed values: user, local, unrestricted.

Enrichment threshold for Kmers.generationMethod 1 and 2. --Kmers.file arg The absolute path of a file containing the k-mers to be used as markers, one per line. A relative path is not accepted.

This should only be used for experimentation on very small runs because it is very time consuming. --Align.alignMethod arg (=3) The alignment method to be used to create the read graph & the marker graph. 0 = old Shasta method, 1 = SeqAn (slow), 3 = banded SeqAn. --Align.maxSkip arg (=30) The maximum number of markers that an alignment is allowed to skip. --Align.maxDrift arg (=30) The maximum amount of marker drift that an alignment is allowed to tolerate between successive markers. --Align.maxTrim arg (=30) The maximum number of unaligned markers tolerated at the beginning and end of an alignment. --Align.maxMarkerFrequency arg (=10) Marker frequency threshold. Markers more frequent than this value in either of two oriented reads being aligned are discarded and not used to compute the alignment. --Align.minAlignedMarkerCount arg (=100) The minimum number of aligned markers for an alignment to be used. --Align.minAlignedFraction arg (=0) The minimum fraction of aligned markers for an alignment to be used. --Align.matchScore arg (=6) Match score for marker alignments (only used for alignment methods 1 and 3). --Align.mismatchScore arg (=-1) Mismatch score for marker alignments (only used for alignment methods 1 and 3). --Align.gapScore arg (=-1) Gap score for marker alignments (only used for alignment methods 1 and 3). --Align.downsamplingFactor arg (=0.10000000000000001) Downsampling factor (only used for alignment method 3). --Align.bandExtend arg (=10) Amount to extend the downsampled band (only used for alignment method 3). --Align.sameChannelReadAlignment.suppressDeltaThreshold arg (=0) 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 meta data fields "runid", "sampleid", and "ch". If any of these meta data fields are missing, this check is suppressed and this option has no effect. --Align.suppressContainments Suppress containment alignments, that is alignments in which one read is entirely contained in another read, except possibly for up to maxTrim markers at the beginning and end. --ReadGraph.creationMethod arg (=0) The method used to create the read graph (0 = undirected, default, 1 = directed, experimental). --ReadGraph.maxAlignmentCount arg (=6) The maximum number of alignments to be kept for each read. --ReadGraph.minComponentSize arg (=100) The minimum size (number of oriented reads) of a connected component of the read graph to be kept.

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.refineThreshold arg (=0) Experimental.

Specify the method used to detangle the assembly graph. 0 = no detangling, 1 = basic detangling.
