May 10-31, 2006

Oh me oh my. I go to conference and come back to a pretty busy mail-list. Of course I added a few comments myself to everything, but that's just because I can't keep anything to myself. Looks like lots of changes and proposed changes to modules, a few new ideas, numerous bug reports, and some good ol' Perl hackery. There's so much now I'll have to break this list summary into a couple of updates, which should be complete by June 6 (fingers crossed!).

First things first...

Announcements

The Deobfuscator

At the top of the list is the availability of the Deobfuscator interface on the BioPerl server, thanks to Mauricio and Dave. What's the Deobfuscator? It's an easy way 'to determine the methods that are available from a given BioPerl module' (directly from the page below):

http://bioperl.org/pipermail/bioperl-l/2006-May/021740.html

And now to the mail lists!

Bioperl-l

Bio::SeqIO oddness

YT points out issues with the way strains and subspecies designations are handled within Bio::SeqIO (via Bio::Species). Torsten chimes in as well; the resolution (though indirect): pull out the information from the 'source' tag from the feature table and look into Bio::Species yet again....

http://bioperl.org/pipermail/bioperl-l/2006-May/021474.html

More fun with primer3

Chen Li and friends (?) continue on with discussion on the idiosyncrasies of using Bio::Tools::Primer3, Bio::Tools::Run::Primer3, and just what is the difference between the two (hint: it's in the name)...

http://bioperl.org/pipermail/bioperl-l/2006-May/021476.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021488.html

Fun(?), annoyances, and confusion with Bio::Species/Bio::Taxonomy::Node/Bio::DB::Taxonomy

Sendu Bala writes in to state his confusion with Bio::Taxonomy::Node and how it handles names. Jason and YT chime in, discussing issues which also relate to Bio::DB::Taxonomy and Bio::Species parsing...

http://bioperl.org/pipermail/bioperl-l/2006-May/021479.html

BioPerl and converting gene predictions to GFF

Torsten responds to an off-list question asking how one can convert several results containing gene predictions to GFF format, giving a bit of code to demonstrate...

http://bioperl.org/pipermail/bioperl-l/2006-May/021502.html

More fun(?) with Bio::DB::Taxonomy

Back for more, Sendu Bala shows that Bio::DB::Taxonomy has problems with certain names at the species level (and possibly below) and posts some potential code as an example. YT agrees and, in a caffeine-induced haze, goes off on all things taxonomic, born of frustrations with species/strain mangling from Bio::Species and Bio::DB::Taxonomy. Nadeem Faruque gives his thoughts as well, including other possible avenues to fix the issue...

http://bioperl.org/pipermail/bioperl-l/2006-May/021505.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021542.html

How not to use BioPerl - Lesson #1

Saurabh Maheshwari asks for help with a complicated script that is meant to look for protein interactions using Bio::Graph modules to look for protein-protein interactions. Of course, this wasn't immediately apparent from the original post, so Marc Logghe and Sean Davis prodded Saurabh for more information. Sean Davis makes further recommendations, while YT gets honest when scrutinizing the submitted code. Lesson learned here? Do not cut-and-paste or copy from various scripts and expect it to work in the way you want...

http://bioperl.org/pipermail/bioperl-l/2006-May/021506.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021524.html

Hilmar responds, requests thought on issues with getting the UniProt database into MySQL (originally posted on BioSQL, see below)...

http://bioperl.org/pipermail/bioperl-l/2006-May/021531.html

Possible memory leak in Bio::SearchIO?

Wayne Clark is worried about the possibility of a memory leak in Bio::SearchIO::blast. YT and Torsten give their thoughts, including the possibility that MySQL is to blame...

http://bioperl.org/pipermail/bioperl-l/2006-May/021540.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021562.html

Bio::DB::Query::GenBank and ID's

Bernd Web finds some potential problems with the way Bio::DB::Query::GenBank and Bio::DB::GenBank handle sequence ID's, including several instances when thrown errors would be helpful and problems with example in the POD. YT explains that this is mainly due to differences between methods used between the two modules and decides to look into it in the future...

http://bioperl.org/pipermail/bioperl-l/2006-May/021553.html

Where's Bio::SeqIO::entrezgene?

Kenny Daily wants to know where to find Bio::SeqIO::entrezgene; YT points out where. Kenny replies back with some problems and Stefan Kirov helps out...

http://bioperl.org/pipermail/bioperl-l/2006-May/021556.html

Formatting sequence output

Chen Li chimes in again with a question about a module for sequence formatting. Malcolm Cook gives him some advice...

http://bioperl.org/pipermail/bioperl-l/2006-May/021565.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021579.html

Bio::Map enhancements

Sendu Bala has posted proposed enhancements to Bio::Map modules in Bugzilla...

http://bioperl.org/pipermail/bioperl-l/2006-May/021570.html

Performance problems and proposed enhancements for BioPerl

YT responded enthusiastically (he's seen issues himself) and Brian O. asked about how the relevant tests responded...

Getting at features and annotation

Nick Staffa wanted to know how to get features and annotation in a GenBank genome file; Brian O., Torsten, and Chandan Singh all give advise (specifically, check the FAQ and the HOWTO's)...

http://bioperl.org/pipermail/bioperl-l/2006-May/021575.html

BioPerl-ext, alignments, and Inline C/XS

Adam Kraut posted a question about how to best 'wrap' a C library for aligning sequences. Aaron Mackey points him towards bioperl-ext and gives some pointers on getting started. Stephen Lenk also chips in with some more advice and a little code...

http://bioperl.org/pipermail/bioperl-l/2006-May/021576.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021587.html

How to parse BLAST XML output

Hubert Prielinger asked how to parse BLAST XML output. Turns out, according to Warren Gish, that WU-BLAST XML and BLAST XML should both be parsed by Bio::SearchIO::blastxml. YT pointed out changes recently to Bio::SearchIO::blastxml that require XML::SAX and XML::SAX::ExpatXS. The next issue was trying to get at taxonomic information, which Jason and YT address...

http://bioperl.org/pipermail/bioperl-l/2006-May/021574.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021595.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021597.html

Bio::Graphics issues

Our old friend Chen Li comes forward with problems concerning Bio::Graphics. Brian O., Torsten, and Lincoln lend a hand...

http://bioperl.org/pipermail/bioperl-l/2006-May/021600.html

Bio::Graph questions

Neil Saunders has problems with using Bio::Graph modules, specifically Bio::Graph::IO and Bio::Graph::ProteinGraph. Brian O. suggests a different (though experimental) set of modules he's donating, called bioperl-network. Brian, has there been an announcement yet?

http://bioperl.org/pipermail/bioperl-l/2006-May/021602.html

Bio::SeqIO::swiss versioning problems

Michael Rogoff points out that Bio::SeqIO::swiss doesn't parse out the sequence version correctly (its on the same line as the date) and proposes a patch. Jason directs him to the proper place to submit patches, but then points out that the date lines needs to have the extra versioning information stripped out. YT also says that the patch doesn't address recent changes as UniProt to the SwissProt format.

http://bioperl.org/pipermail/bioperl-l/2006-May/thread.html

Bio::SeqFeature::Tools::Unflattener problems

Barry Moore uncovers a nasty bug with Unflattener, and YT confirms. Another one for Bugzilla...

http://bioperl.org/pipermail/bioperl-l/2006-May/021610.html

Bio::Graphics problems (it's like I'm hearing an echo...)

http://bioperl.org/pipermail/bioperl-l/2006-May/021600.html

Bio::Restriction::IO...

Derek Fairley asks about using Bio::Restriction::IO::bairoch. Though he got no direct answer from the mail list, the same question was posited again (see below).

http://bioperl.org/pipermail/bioperl-l/2006-May/021617.html

Bio::Assembly::IO::ace output

Rowan Mitchell wants to know if write output is to be implemented for Bio::Assembly::IO::ace. Robson Francisco de Souza replies back that there are no current plans to add a write method for this module since it wasn't needed when originally submitted...

http://bioperl.org/pipermail/bioperl-l/2006-May/021618.html

Getting files in EMBL format

Chen Li wants to know how to download files directly from EMBL. No one responds. Poor Chen...

http://bioperl.org/pipermail/bioperl-l/2006-May/021622.html

Bio::Graphics::Panel negative position numbering

Kevin Lam Koiyau wants to know how to get negative position numbering with Bio::Graphics::Panel. Lincoln indicates that this is possible under bioperl 1.5.1. Jonathan Epstein adds a second question on how to add directional arrows to for BLAST hits, but no one answers.

http://bioperl.org/pipermail/bioperl-l/2006-May/021625.html

http://bioperl.org/pipermail/bioperl-l/2006-May/021640.html

...and Bio::Restriction::IO again

Jelena Obradovic points out problems with converting a REBASE file into a Bio::Restriction::EnzymeCollection object. YT points out the format is not captitalized, but find that the normal format ('bairoch') dies with an error. Brian points out that the format name should be more forgiving of case but YT indicates that case is the least of the issues here...

http://bioperl.org/pipermail/bioperl-l/2006-May/021632.html

Bio::Tools::Run::StandAloneBlast

Genevieve DeClerck is trying to work out how to combine several analyses while parsing through a BLAST report. Brian O. and Torsten lends a hand, and Sendu Bala gives some input on a possible solution.

http://bioperl.org/pipermail/bioperl-l/2006-May/021646.html

Using and integrated server to grab output from multiple servers

Orphan : Shameer Khadar wants to know how to get a system set up for grabbing output from multiple servers for display on an integrated server. Shameer, never start your question with 'My query may not be directly related to BioPERL', as we might lose interest...

http://bioperl.org/pipermail/bioperl-l/2006-May/021648.html

Bio::Graphics::Panel backgroud color

Orphan : Jelena Obradovic wants to know how to turn off the backgraound color of the panel.

CVS and code auditing

Torsten Seemann stirs up a hornet's nest with an audit regarding the use of 'return undef;' in the core code based on a suggestion made by Damian Conway in Perl Best Practices. Pretty much everybody (where's Jason?!?) gives an opinion on the issue; YT kicks the nest around a bit more by pointing out how many 'throw_not_implemented statements are found in regular (non-interface) code. How fun!

http://bioperl.org/pipermail/bioperl-l/2006-May/021651.html

Bio::TreeIO "Collapse" function

Lucia Peixoto ponders on how to collapse any node in a tree. Aaron Mackey and Jason suggest solutions. Lucia has a few more questions. I have a question Lucia: what exactly is the "ass_Descendent" method? Couldn't find that one in POD...

http://bioperl.org/pipermail/bioperl-l/2006-May/021658.html

Moving the tutorial to the wiki

Jay Hannah tries moving the Bioperl tutorial instructions to the wiki and finds out how tricky it can be. Brian O., YT, and Mauricio all join in on trying to decide whether to keep the entire script or to split the documentation from the script completely...

http://bioperl.org/pipermail/bioperl-l/2006-May/021670.html

How to add methods to a module

Hongyu Zhang wants to donate code to add to Bio::SimpleAlign but doesn't know how. YT modifies the FAQ (sneaky!) and points him to it...

http://bioperl.org/pipermail/bioperl-l/2006-May/021683.html

BioSQL-l

Problems loading uniprot release 49.6 into mysql

S. Rayner (if that is your real name) relays problems gettng Uniprot loaded into MySQL. An issue with the 'RL' line is located in SwissProt files in which the annotation isn't unique. Hilmar suggests a few things to work around that and suggests several possible fixes...

http://lists.open-bio.org/pipermail/biosql-l/2006-May/000977.html

load_seqdatabase.pl errors and GenBank-mangled UniProt files

Gerben Menschaert submits a problem with loading a GenBank sequence. Hilmar points out that the file in question is a UniProt file and that the GenBank parser has problems with these files, then suggests loading the UniProt files using the SwissProt format.

http://lists.open-bio.org/pipermail/biosql-l/2006-May/000983.html

BioSQL and gbrowse

Genevieve DeClerck says she's having problems getting BioSQL to work with Gbrowse. Hilmar has a few suggestions...

Problem with adding features under BioSQL

Michael Cipriano finds an issue with BioSQL and adding features under GBrowse. Hilmar is confused (it IS BioSQL-l, not the GBrowse list). Lincoln posts a fix for the issue.

http://lists.open-bio.org/pipermail/biosql-l/2006-May/000987.html

Bioperl-guts-l (for the diehards)

Note: Significant module changes and additions to CVS are normally announced on the main bioperl-l list if they are in decent enough condition for production work. If modules listed below have not been announced, then there may be a very good reason for it. If you plan on trying to use these, consider contacting the author(s). Many of the modules discussed in this section are highly experimental and are in various stages of development. They may or may not work at all. Therefore, we are not responsible for any problems faced with using this code.

I'm trying out a new layout this week which will hopefully enable me to keep up with all the changes a bit easier (I'm using a script to consolodate this stuff). Let me know what you think.
