> Hi,

> I made a TranscriptDb object, which worked fine when I use it in the same R

> session. I got an error like following:
> 
> > txdb <- makeTranscriptDb (transcripts, splicings, chrominfo=chrominfo)
> > save(txdb, file="a.rda")
> 
> ... quit R and rerun R
> 
> > load("a.rda")
> > feature.cds <- cds(txdb, columns="exon_name")
> Error in sqliteExecStatement(con, statement, bind.data) :
>   RS-DBI driver: (expired SQLiteConnection)
> 
> What do I have to reuse a TranscriptDb object in another R session?
