[EMBOSS] Bug in extractfeat ?

[Charles Plessy]

Dear EMBOSS developers,

I have used extractfeats in EMBOSS 6.4 to extract some features of GenBank
files with commands like the following.

    $ extractfeat TRG at .gb -filter -join TRUE -tag 'standard_name' -value "TRGC1" -describe standard_name -osformat2 fasta 
    >NG_007033_36562_39077 [C_region] (standard_name="TRGC1") Mus musculus T cell receptor gamma chain (Tcrg) on chromosome 13.

However, with EMBOSS 6.6, there is no output anymore.

    $ extractfeat TRG at .gb -filter -join TRUE -tag 'standard_name' -value "TRGC1" -describe standard_name -osformat2 fasta
    Warning: No sequences written to output file 'stdout'

The TRG at .gb file was downloaded from NCBI's website and a copy is available at
the following URL.

    http://source.clonotyper.branchable.com/?p=source.git;a=blob;f=references/TRG@.gb;h=9d48fafbb7e4209a462dbb1ab552195c00e920e3;hb=HEAD

The commands ran on a Debian system with the Debian packages 6.4.0-2 or
6.6.0-1.

Is that a bug in EMBOSS > 6.4 ?

Have a nice day,

Charles Plessy
