[BioC] intron sequences from biomaRt

[Durinck, Steffen (NIH/NCI) [F]]

Dear Dario,

No there is currently no possibility to select intronic sequences directly.  You could request this at helpdesk at ensembl.org and see if they want to add this feature in future versions of Ensembl.  For now the only way to do it with biomaRt would be to retrieve the transcript or gene sequences and the exon sequences and then find the intronic sequences by splitting the transcript sequences on the different exons.  

Hope this helps,
Steffen

dear list,

i need to get the intron sequences for a group of entrez gene ids.
is there any way to do it using biomaRt? apparently there is no option in the 
getSequence() function.

> sessionInfo()
R version 2.5.0 (2007-04-23)
i686-redhat-linux-gnu
 biomaRt    RCurl      XML
"1.10.0"  "0.8-1"  "1.7-3"

any suggestions?
thanks for your help.

yours
