[ensembl-dev] "subseq" error

[S Venkata Suresh Kumar]

Hi All

When i am trying to convert a hgvs file to vcf file, I am getting
following error:

"Can't call method "subseq" on an undefined value at
/opt/vep/ensembl-variation/modules/Bio/EnsEMBL/Variation/DBSQL/VariationFeatureAdaptor.pm
line 1272, <GEN0> line 1."

any clues ?

I am using vep 2.4, OS linux, bioperl 1.6.901-2.

regards
vs
