Problem for retrieving gene symbol from ID_REF

Question

[fahim]

Hi I tried to analyse a geo data set by limma.All are going good but i am unable to get gene symbol from that dataset .The dataset first column are Refrence ID .So my question is how can i retrieve gene symbol from this kind of dataset.

[GenoMax]

Provide ID examples when asking questions about them. Without those it is virtually impossible to get a good answer.

I am talking about-PH_hs_0000002 this type of id

Looks like this is Phalanx Human One Array. As @Nitin suggested you can find the GPL annotation provided at NCBI.

@GenoMax is right.

But I will try to answer it virtually and I assume it is microarray data.

So either you can find the ids and associated gene annotation (gene symbol, gene name, etc) in the GPL table under Platforms section in the GEO record OR you can use the R package (array specific OR biomaRt) to annotate the Ids.

[fahim]

you mean to say array specific??I found a package array in searching google.

Something like this, hgu133a.db. But in my opinion, the GPL file submitted to GEO would be a better option, I mean at least I use that information over others.
