NAME
gmap - Genomic Mapping and Alignment Program
SYNOPSIS
gmap -dDB|-gFASTA [OPTION]... [QUERY]...
DESCRIPTION
Align the sequences QUERY to the reference, specified with -d or -g. With no QUERY, read standard input.
OPTIONS
Input options
-D, --dir=directory
Genome directory
-d, --db=STRING
Genome database. If argument is '?' (with the quotes), this command lists available databases.
-k, --kmer=INT
kmer size to use in genome database (allowed values: 16 or less). If not specified, the program
will find the highest available kmer size in the genome database
--basesize=INT
Base size to use in genome database. If not specified, the program will find the highest
available base size in the genome database within selected k-mer size
--sampling=INT
Sampling to use in genome database. If not specified, the program will find the smallest
available sampling value in the genome database within selected basesize and k-mer size
-G, --genomefull
Use full genome (all ASCII chars allowed; built explicitly during setup), not compressed version
-g, --gseg=filename
User-supplied genomic segment
-1, --selfalign
Align one sequence against itself in FASTA format via stdin (Useful for getting protein
translation of a nucleotide sequence)
-2, --pairalign
Align two sequences in FASTA format via stdin, first one being genomic and second one being cDNA
--cmdline=STRING,STRING
Align these two sequences provided on the command line, first one being genomic and second one
being cDNA
-q, --part=INT/INT
Process only the i-th out of every n sequences e.g., 0/100 or 99/100 (useful for distributing jobs
to a computer farm).
--input-buffer=INT
Size of input buffer (program reads this many sequences at a time for efficiency) (default 1000)
Computation options
-B, --batch=INT
Mode Offsets Positions Genome
0 allocate mmap mmap
1 allocate mmap & preload mmap
2 allocate mmap & preload mmap & preload (default)
3 allocate allocate mmap & preload
4 allocate allocate allocate
5 expand allocate allocate
Note: For a single sequence, all data structures use mmap. If mmap not available and allocate not
chosen, then will use fileio (very slow)
--nosplicing
Turns off splicing (useful for aligning genomic sequences onto a genome)
--min-intronlength=INT
Min length for one internal intron (default 9). Below this size, a genomic gap will be considered
a deletion rather than an intron.
-K, --intronlength=INT
Max length for one internal intron (default 1000000)
-w, --localsplicedist=INT
Max length for known splice sites at ends of sequence (default 200000)
-L, --totallength=INT
Max total intron length (default 2400000)
-x, --chimera-margin=INT
Amount of unaligned sequence that triggers search for the remaining sequence (default 40).
Enables alignment of chimeric reads, and may help with some non-chimeric reads. To turn off, set
to a large value (greater than the query length).
-t, --nthreads=INT
Number of worker threads
-C, --chrsubsetfile=filename
User-supplied chromosome subset file
-c, --chrsubset=string
Chromosome subset to search
-z, --direction=STRING
cDNA direction (sense_force, antisense_force, sense_filter, antisense_filter, or auto (default))
-H, --trimendexons=INT
Trim end exons with fewer than given number of matches (in nt, default 12)
--cross-species
For cross-species alignments, use a more sensitive search for canonical splicing
--canonical-mode=INT
Reward for canonical and semi-canonical introns 0=low reward, 1=high reward (default), 2=low
reward for high-identity sequences and high reward otherwise
--allow-close-indels=INT
Allow an insertion and deletion close to each other (0=no, 1=yes (default), 2=only for high-
quality alignments)
--microexon-spliceprob=FLOAT
Allow microexons only if one of the splice site probabilities is greater than this value (default
0.90)
--cmetdir=STRING
Directory for methylcytosine index files (created using cmetindex) (default is location of genome
index files specified using -D, -V, and -d)
--atoidir=STRING
Directory for A-to-I RNA editing index files (created using atoiindex) (default is location of
genome index files specified using -D, -V, and -d)
--mode=STRING
Alignment mode: standard (default), cmet-stranded, cmet-nonstranded, atoi-stranded, or atoi-
nonstranded. Non-standard modes requires you to have previously run the cmetindex or atoiindex
programs on the genome
-p, --prunelevel
Pruning level: 0=no pruning (default), 1=poor seqs, 2=repetitive seqs, 3=poor and repetitive
