RMAP

  • RMAP : designed for Illumina-Solexa
  • Command: rmap
 rmap         -m 3 -w 33                            -c Pa.1con    Pa.seq -o Pa.rmap

SHRiMP

  • Web site
  • Commands: rmapper-cs , rmapper-ls, ...

SeqMap

  • SeqMap developed at Stanford
  • allows up to five mixed substitutions and inserted/deleted nucleotides in the mapping
  • allows sequences to contain N’s, and to have unequal lengths
 ./seqmap
 Usage: seqmap <number of mismatches> <probe FASTA file name> <transcript FASTA file name> <output file name> [options]
 
 Parameters:
 <number of mismatches>                          maximum edit distance allowed
 <probe FASTA file name>                         probe/tag/read sequences
 <transcript FASTA file name>                    reference sequences
 <output file name>                              name of the output file
 ...

SOAP

 soap         -v 5                                  -d Pa.1con -a Pa.seq -o Pa.soap

SSAHA

  • Web site(Sanger)
  • Focused on exact, nearly exact matches
  • Does not find all the exact matches???
  • Example: Solexa 33bp ~30% of reads are not found
