build without D causes IgBlast to crash

[scharch]

The documentation for build indicates that D_seqs is an optional argument. However, if it is omitted, bracer assemble submits an invalid command to IgBlast that causes a crash:

Traceback (most recent call last):

because /nethome/schrammca/bracer/resources/Hpseud/igblast_dbs/BCR_D.fa is empty and there is no associated blastdb.

Related: --V_gapped is also documented as optional, but bracer assemble doesn't test for the absence of the gapped files and so this also causes a crash.

Hi @scharch ,
Thanks for your feedback. I will look into this issue in the coming days. Did you try creating resources for heavy chain without D sequences, or was it light chain?

[scharch]

I ran bracer build for all 3 loci before attempting bracer assemble.

I see now that the documentation for build was too vague. What I meant was that D sequences were optional in the sense that they are not needed for light chains. However, they are needed for heavy chains. I will update the documentation accordingly. I will also look into the crash caused by absence of V_gapped sequences.
