I would like to do a differential gene expression analysis on a microarray data. From the literature, I understood, call detection (Present, Absent, Marginal) has to be done to minimize false positives. I found this tutorial for the call detection and also to find the DEGs, from .cel files.
For this particular dataset used for my study, .cel file is unavailable and only .txt file/ SOFT file is available for download.
- Can call detection be done from these files?
- Or is there any other method/ package that can be used for the same?
