bioperl blast parsing problem

[Mark]

We recently upgraded our installation of blast from v2.2.19 to blast+ 2.2.26 and I have found that my bioperl blast xml parsers no longer work properly (typically they return some form of truncated result). Has anyone else encountered this and if this is a known problem have either the NCBI or BioPerl folks provided a solution.

Thanks

Mark

Which release of BioPerl are you using?

version 1.006901

Can't really help you there but have you considered other output formats (e.g. outfmt 6) and simply parsing your files with unix commands?

Unfortunately, you can't get the hit description via that method, a serious shortcoming.

What do you mean by hit description? There are like 40 fields to choose from..

Subject description. Yes I know you could grab the oridinal ID and the go back to the blastdb and pull out the record and parse it's description from there but that's a bit of a pain so I would rather find out if there is a solution to the parsing of the xml output.

You mean stitle/salltitles? But yeah, 2.2.28+ only.

[Mark]

Yea, I know but I don't do the blast updates for our system and so can't take that route to a fix. Thanks for trying to help though.

Maybe your problem is related to an outdated XML::SAX? (first note). Just an idea..
