Hi, I have a question on how to identify transcript names in processed data from Array Express. I saved the processed data from this study: (E-GEOD-24395) and I got some files each one with three columns (reporter identifier, expression value and p-value).
Is there any way to find the transcript name (something similar to gene symbols) corresponding to the reporter identifiers? I searched for some of these reporter identifiers into all files provided within the study (simply opening each file and then doing ctrl+F) but I couldn't fine them anywhere. So, the problem is that I don't really know what these "Reporter identifiers" are...
I also noticed that the file named "A-MEXP-930.adf.txt" (where I can get the hugo IDs) is exactly the same length as the processed files (48,701 rows after removing the header), so I guess I could combine in a data frame the hugo IDs extracted from this file with the expression values for each sample from the other files, but I am not sure about the correspondence between hugo IDs and the reporter identifiers (the listed hugo IDs could have been sorted or manipulated someway, and there are also some blank values when I read them as a table in R).
Any help? Thanks
