Bioperl: running local blasts
Fri, 23 Jun 2000 13:20:06 -0400
Okay, so I've done a bit more tinkering, and here's a really strange thing.
I wrote a function called _test_me which just prints "testing" and put this
function in Bio/Root/RootI.pm right after where _rearrange is defined. Next,
in Bio/Root/Object.pm (which inherits from RootI.pm), I added &_test_me to
the @EXPORT_OK array, right after &_rearrange. Finally, in LocalBlast.pm I
changed the line
use Bio::Root::Object qw(&_rearrange);
use Bio::Root::Object qw(&_rearrange &_test_me);
and placed a call to _test_me right above the call to _rearrange inside
blast_local. So basically I've created a function that is defined,
inherited, etc. exactly as _rearrange is. And guess what happens? The
_test_me function is found and executes but the _rearrange call generates
the undefined subroutine error.
So then I noticed that _rearrange is called again later in the code, but as
(in _set_options) and so I changed the call in blast_local to be
and this generated the error:
*** 1 Blast reports produced fatal errors:
Can't run local BLAST: failed to obtain parameters using _rearrange().
Make sure that the first argument is a Bio::Tools::Blast.pm object.
at /local/lib/perl/lib/Bio/Tools/Blast.pm line 1284
If it makes any difference I'm running Solaris 2.5.1
