Description

censor compares and masks protein or nucleotide sequences.

There are 2 compilations of censor - one comes with a copy of repbase :

censor-v.v.vv.tar.gz

another one includes only software :

censor-norb-v.v.vv.tar.gz

You need to install wu-blast or ncbi-blast package to use censor.

Censor package includes two scripts. One, called censor, is designed to run with the licensed, full-featured version of wu-blast (censor was tested with wu-blast that was available from Washington University before it was sold to Advanced Biocomputing, LLC). Another executable, censor.ncbi, has settings modified to work with ncbi-blast.

Looks like wu-blast, now ab-blast, is no longer available for free for academic users. For those users who don't have wu-blast the only way to use censor is to use censor.ncbi. Your feedback is welcomed to improve censor's performance with ncbi-blast.

Changelog

4.2.21 -> 4.2.22
- Forced proper handling of tab symbols in fasta definition line by blastall by adding "-J T" option.

4.2.20 -> 4.2.21
- Added handling of non-unix style ends of lines.

4.2.19 -> 4.2.20
- Modified parameters to blastall to give more consistent results with blastn algorithm. For some reason blastn program misses significant hits with wordsizes below 9. Wordsize (-W) is set to be 9-11 depending on sensitivity modes.
