GraphMap was also designed for ease-of-use: the default parameters can handle a wide range of read lengths and error profiles, including: Illumina, PacBio and Oxford Nanopore.
This is an especially important feature for technologies where the error rates and error profiles can vary widely across, or even within, sequencing runs.

Usage:
graphmap [options] -r <reference_file> -d <reads_file> -o <output_sam_path>

Usage:
graphmap [options]

Options
Input/Output options:
-r, --ref STR Path to the reference sequence (fastq or fasta).
-i, --index STR Path to the index of the reference sequence. If not specified, index is generated in
the same folder as the reference file, with .gmidx extension. For non-parsimonious
mode, secondary index .gmidxsec is also generated.
-d, --reads STR Path to the reads file.
-o, --out STR Path to the output file that will be generated.
--gtf STR Path to a General Transfer Format file. If specified, a transcriptome will be built
from the reference sequence and used for mapping. Output SAM alignments will be in
genome space (not transcriptome).
-K, --in-fmt STR Format in which to input reads. Options are:
auto - Determines the format automatically from file extension.
fastq - Loads FASTQ or FASTA files.
fasta - Loads FASTQ or FASTA files.
gfa - Graphical Fragment Assembly format.
sam - Sequence Alignment/Mapping format. [auto]
-L, --out-fmt STR Format in which to output results. Options are:
sam - Standard SAM output (in normal and '-w overlap' modes).
m5 - BLASR M5 format. [sam]
-I, --index-only - Build only the index from the given reference and exit. If not specified, index will
automatically be built if it does not exist, or loaded from file otherwise. [false]
--rebuild-index - Always rebuild index even if it already exists in given path. [false]
--auto-rebuild-index - Rebuild index only if an existing index is of an older version or corrupt. [false]
-u, --ordered - SAM alignments will be output after the processing has finished, in the order of
input reads. [false]
-B, --batch-mb INT Reads will be loaded in batches of the size specified in megabytes. Value <= 0 loads
the entire file. [1024]

General-purpose pre-set options:
-x, --preset STR Pre-set parameters to increase sensitivity for different sequencing technologies.
Valid options are:
illumina - Equivalent to: '-a gotoh -w normal -M 5 -X 4 -G 8 -E 6'
overlap - Equivalent to: '-a anchor -w normal --overlapper --evalue 1e0
--ambiguity 0.50 --secondary'
sensitive - Equivalent to: '--freq-percentile 1.0 --minimizer-window 1'

Alignment options:
-a, --alg STR Specifies which algorithm should be used for alignment. Options are:
sg - Myers' bit-vector approach. Semiglobal. Edit dist. alignment.
sggotoh - Gotoh alignment with affine gaps. Semiglobal.
anchor - anchored alignment with end-to-end extension.
Uses Myers' global alignment to align between anchors.
anchorgotoh - anchored alignment with Gotoh.
Uses Gotoh global alignment to align between anchors. [anchor]
-w, --approach STR Additional alignment approaches. Changes the way alignment algorithm is applied.
Options are:
normal - Normal alignment of reads to the reference.
(Currently no other options are provided. This is a placeholder for future features,
such as cDNA mapping) [normal]
--overlapper - Perform overlapping instead of mapping. Skips self-hits if reads and reference files
contain same sequences, and outputs lenient secondary alignments. [false]
--no-self-hits - Similar to overlapper, but skips mapping of sequences with same headers. Same
sequences can be located on different paths, and their overlap still skipped. [false]
-M, --match INT Match score for the DP alignment. Ignored for Myers alignment. [5]
-X, --mismatch INT Mismatch penalty for the DP alignment. Ignored for Myers alignment. [4]
-G, --gapopen INT Gap open penalty for the DP alignment. Ignored for Myers alignment. [8]
-E, --gapext INT Gap extend penalty for the DP alignment. Ignored for Myers alignment. [6]
-z, --evalue FLT Threshold for E-value. If E-value > FLT, read will be called unmapped. If FLT < 0.0,
thredhold not applied. [1e0]
-c, --mapq INT Threshold for mapping quality. If mapq < INT, read will be called unmapped. [1]
--extcigar - Use the extended CIGAR format for output alignments. [false]
--no-end2end - Disables extending of the alignments to the ends of the read. Works only for
anchored modes. [false]
--max-error FLT If an alignment has error rate (X+I+D) larger than this, it won't be taken into
account. If >= 1.0, this filter is disabled. [1.0]
--max-indel-error FLT If an alignment has indel error rate (I+D) larger than this, it won't be taken into
account. If >= 1.0, this filter is disabled. [1.0]

Algorithmic options:
-k INT Graph construction kmer size. [6]
-l INT Number of edges per vertex. [9]
-A, --minbases INT Minimum number of match bases in an anchor. [12]
-e, --error-rate FLT Approximate error rate of the input read sequences. [0.45]
-g, --max-regions INT If the final number of regions exceeds this amount, the read will be called
unmapped. If 0, value will be dynamically determined. If < 0, no limit is set. [0]
-q, --reg-reduce INT Attempt to heuristically reduce the number of regions if it exceeds this amount.
Value <= 0 disables reduction but only if param -g is not 0. If -g is 0, the value of
this parameter is set to 1/5 of maximum number of regions. [0]
-C, --circular - Reference sequence is a circular genome. [false]
-F, --ambiguity FLT All mapping positions within the given fraction of the top score will be counted for
ambiguity (mapping quality). Value of 0.0 counts only identical mappings. [0.02]
-Z, --secondary - If specified, all (secondary) alignments within (-F FLT) will be output to a file.
Otherwise, only one alignment will be output. [false]
-P, --double-index - If false, only one gapped spaced index will be used in region selection. If true,
two such indexes (with different shapes) will be used (2x memory-hungry but more
powerful for very high error rates). [false]
--min-bin-perc FLT Consider only bins with counts above FLT * max_bin, where max_bin is the count of
the top scoring bin. [0.75]
--bin-step FLT After a chunk of bins with values above FLT * max_bin is processed, check if there
is one extremely dominant region, and stop the search. [0.25]
--min-read-len INT If a read is shorter than this, it will be marked as unmapped. This value can be
lowered if the reads are known to be accurate. [80]
--minimizer-window INT Length of the window to select a minimizer from. If equal to 1, minimizers will be
turned off. [5]
--freq-percentile FLT Filer the (1.0 - value) percent of most frequent seeds in the lookup process. [0.99]
--fly-index - Index will be constructed on the fly, without storing it to disk. If it already
exists on disk, it will be loaded unless --rebuild-index is specified. [false]

Other options:
-t, --threads INT Number of threads to use. If '-1', number of threads will be equal to min(24, num_cores/2). [-1]
-v, --verbose INT Verbose level. If equal to 0 nothing except strict output will be placed on stdout. [5]
-s, --start INT Ordinal number of the read from which to start processing data. [0]
-n, --numreads INT Number of reads to process per batch. Value of '-1' processes all reads. [-1]
-h, --help - View this help. [false]

Debug options:
-y, --debug-read INT ID of the read to give the detailed verbose output. [-1]
-Y, --debug-qname STR QNAME of the read to give the detailed verbose output. Has precedence over -y. Use
quotes to specify.
-b, --verbose-sam INT Helpful debug comments can be placed in SAM output lines (at the end). Comments can
be turned off by setting this parameter to 0. Different values increase/decrease
verbosity level.
0 - verbose off
1 - server mode, command line will be omitted to obfuscate paths.
2 - umm this one was skipped by accident. The same as 0.
>=3 - detailed verbose is added for each alignment, including timing measurements and
other.
4 - qnames and rnames will not be trimmed to the first space.
5 - QVs will be omitted (if available). [0]
