There is a wiki page about bioperl programming conventions as well: http://www.bioperl.org/wiki/html/BioPerl/BioperlProgrammingConventions.html

Wow, this took me quite something to find it. How come the front page is BioMoby??? Noone's going to be able find anything anymore.

> Hello all, I need some advice.
> I work at the Arizona Genomics Institute under Dr. Cari Soderlund (if

> developed FPC - FingerPrinted Contigs - probably the most 
> used software
> for physical map construction.  She's here in Tucson, AZ after a short
> hiatus in Clemson, SC)  Anyway, I've re-introduced our group 
> to Bioperl
> and we are starting to take advantage of it whereever possible.  Cari
> had seen Bioperl before, but that was pre 1.0 days, when 
> things weren't
> stable enough (in her opinion) for a production environment, 
> after which
> point, she never got around to looking into it again.
> I noticed in some document from a presentation given by one of the
> Bioperl bigwigs (might have been LStein), that a FPC parser 
> was a common
> request.  If that's true, we know fpc probably as well as anybody else
> so it would make sense for us to develop/maintain it.
> So now we would like to make a contribution.  Don't get too excited
> yet... It's not programmed yet.  But we have found that in many, many
> different areas we need to read a .fpc file (and corresponding .cor
> file) and Do Something(c) with it.  At the same time, I want 
> to get more
> familiar with Bioperl.  I've done fairly simple things, like 
> reading in
> fasta/genbank/swisspro format files and working with 
> alignments (as you
> all saw in my EST Alignment questions).
> The advice I want is as follows:
> 1) Where are the standards/guidelines for writing Bioperl modules?
> 2) Any ideas on what features/functionality Bio::FPC should have?
> 3) Any ideas on what (if any besides Bio::Root) I should inherit from?
> 4) Should this be an interface and separate implementation or just an
> implementation?
>    (i.e., are there other file formats/programs for physical maps?)
> 5) What Bioperl objects should I use in construction?
> These are the ideas I have so far (after all of a day of 
> thinking about
> it, so feel free to laugh/scorn/suggest better implementations)
> (all these classes should be prefixed with Bio::FPC
> 1) ::Project
>   This would be the main class.  It would contain the 
> information parsed
> from the top 8 or so lines of the .fpc file.  It would also 
> contain the
> rest of these objects.
> 2) ::Clone
>   Obviously, this is the clone (or more properly - 
> fingerprinted clone)
> from the fpc file.  The attributes would include type (Clone, 
> name, bands[], sizes[] (if available), a few dates (creation,
> modification), remarks (normal and fpc remarks), contig (and range),
> matching clones (parents and children; approximate, exact, 
> and pseudo),
> markers, etc.  Basically anything you might find as the 
> /^(\w+)/ of the
> line in a .fpc file.
>   In typing that out, it seems that maybe the contig and range that a
> clone hits would best be implemented as a type of RangeI 
> class, which is
> more apparent now that I typed that sentence.  Moving on then...
> 3) ::Contig
>   Contig number, datetime, status (Ok, NoCB, Avoid, NoAce, 
> Dead), #Q's,
> description.
> 4) ::Marker
>   Type (STS, eMRK, whatever), date (create,mod), Global position (if
> anchored to framework)
> That's basically it for the objects.  Although the contigrange might
> need to be an object inherited from RangeI.  
> So now I need some input, and we'll see if I can't get started coding
> this.
> Thanks!
