I have a set of transcripts cluster IDs from Affimetrix (Human gene 1xST) and I would like to download the sequences to BLAST them. These have no annotations and I 'd like to find annotations where possible.
Does anyone know an easy way to download the sequences from a list of transcript ID ? I downloaded the transcripts and probesets CSV files but they do not contain the sequences. Is there another file that I didn't see that contain the sequences ?
At the moment I need to look for each cluster in Affimetrix, get the sequence, BLAST it, and start again for next cluster. Surely there is a better way to do that.
Any suggestion would be greatly appreciated.
