Question

[64bga]

Hi everybody,

I'm new in microarrays analysis and I have some HuGene-1_0-st-v1 .CEL files and I wanna use it to do some Pathways analysis with David or GSEA. My .CEL has the following probeset_id:

7896737
7896739
7896741
7896743
7896745
7896747
7896749
7896751

and I need something like that:

1007_s_at
1053_at
117_at

because I am not able to use in David.

Thanks in advance!!

You need to convert your HuGene probeset IDs to something that DAVID can use (e.g. Ensembl Gene IDs) - not to different probeset IDs.

DAVID provides an ID conversion tool, but it looks like HuGene IDs can't be used as input. So your answer is "BioMart". There are multiple answers on this site about how to use it. Search for them, see if they help, post a comment here if not.
