cummeRbund error genes.gene_id

[jutri]

Hi,

I am trying to use cummeRbound and I am getting the following error:

Error in sqliteExecStatement(con, statement, bind.data) :
RS-DBI driver: (RS_SQLite_exec: could not execute: genes.gene_id may not be NULL)

I generated the data with cufflinks V.2.1 and using cummeRbound V. 2.0

thanks,

Jose
