[Bioperl-l] Error while running load_seqdatabase.pl

Hi Hilmar,
   
  I am extremely sorry about sending such a huge file, I realized only after I sent it. Really sorry....
   
  And, finally, the loading worked. I set the primary_id, accession and the display_id to the first number on my file, and it loads perfectly fine now! 
   
  Thank you so much Hilmar for all the help. 
   
  George.

  Hi George,  

  your reply to mine contained a plain-text file attachment of (roughly) 8MB. Not only does it hang up my email reader (probably because it recognizes the files as text and tries to display it), but you also sent it to the entire list, resulting in 8MB being sent to around 1600 people. 
  

  Please, whenever you have larger files, only send it to an individual, *never* to a mailing list unless specifically asked to do so.
  

  Second, whenever you have large text files to attach, *always* compress them. This will typically save 70% of the bandwidth being used for transmission.
  

  What I could recover from your file looked like the first element is unique. It also looks like the last 4 elements are the accession of the target sequence (presumably of a GenBank entry - presumably maize BAC clones?) and the start and end coordinates and the strand.
  

  All of display_id, accession_number, and primary_id must be 40 chars or less (sorry for not pointing that out right away), so you may use the first element for all three of them. You could also use some combination of the other elements to construct a more meaningful display_id, just don't exceed 40 chars.
  

  Setting primary_id() to undef should definitely work. If it doesn't you may be using an old version of Bioperl. You should be using release 1.5.2, or at least 1.5.x. It's possible that the 1.4 release still had the bug of not allowing the setting to undef, please upgrade if that's the version you're using.
  

  Let me know if you still have problems with getting this to work.

    Hi Hilmar,
   
  I have been trying to get around this problem for some days now, but havent had much luck. My file has about 12000 odd records, and when I try to load it with a pipeline to the package, I have about 483 records that get loaded. 
   
  sub process_seq
{
  my ($self, $seq) = @_;
#  $seq->accession_number($seq->display_id);
  my @ids = split(/\|/,$seq->display_id);
  $seq->accession_number($ids[0]);
  $seq->primary_id($ids[2]);
  return ($seq);
}

  I am assuming this is because I use the ids[2] for the primary_id, and possibly the file has 483 unique records for that field. When I use some other reference like ids[3] etc(coz it has more unique values), I get the same error about the length being more than 40. 
   
  I printed out the values for the display_id, primary_id and accession_number. The display_id has the entire first line of the file, so does the primary_id, if I dont set it in my new script. The accession number is split correctly and printed. 
   
  This is how the first few lines in my file look like,

  That's odd indeed. Did you try and put a print statement before the 
return statement that proves that 1) the codes gets executed, and 2) 
display_id(), primary_id() and accession_number() have the expected 
values?

BTW you might also want to set primary_id() to undef (as the ID found 
in the FASTA files doesn't really count as a primary database- 
specific ID anyway). The identifier column in bioentry (which 
primary_id() maps to) is constrained to 40 chars as well.
