NAME¶
tantan - low complexity and tandem repeat masker for biosequences
SYNOPSIS¶
tantan [options] fasta-sequence-file(s)
DESCRIPTION¶
Find simple repeats in sequences
Options (default settings):¶
- -p
- interpret the sequences as proteins
- -x
- letter to use for masking, instead of lowercase
- -c
- preserve uppercase/lowercase in non-masked regions
- -m
- file for letter-pair score matrix
- -r
- probability of a repeat starting per position (0.005)
- -e
- probability of a repeat ending per position (0.05)
- -w
- maximum tandem repeat period to consider (100, but -p selects 50)
- -d
- probability decay per period (0.9)
- -i
- match score (BLOSUM62 if -p, else 2 if -f4, else 1)
- -j
- mismatch cost, 0 means infinite (BLOSUM62 if -p, else 7 if -f4, else 1)
- -a
- gap existence cost (0)
- -b
- gap extension cost, 0 means no gaps (7 if -f4, else 0)
- -s
- minimum repeat probability for masking (0.5)
- -n
- minimum copy number, affects -f4 only (2)
- -f
- output type: 0=masked sequence, 1=repeat probabilities,
- 2=repeat counts, 3=BED, 4=tandem repeats (0)
- -h, --help
- show help message, then exit
- --version
- show version information, then exit
