Hello everyone! I want to analyze together the gene expression profiles from two different datasets and compare a number of genes between the two. One of them is in rsem v2 output format, and the other in fpkm (cufflink output). I have triend calculating the fpkm from rsem raw counts, but the distributions do not correlate at all so I am not sure if it would be possible to compare the gene expression among them as the data do not seem to be in the same scale.
Do you have any idea if it is possible to make these two data type comparable?
Thank you in advance,
Sandra
Thank you Kevin, I will go for it. Yes I want to merge the two datasets. We are also thinking of asking for the permissions to have the bam files of the second dataset so I will be able to re-analyze them with the same software.
Great!
Well, the BAM files would help, but they would still be produced very differently, i.e., a BAM produced by Bowtie/TopHat is very different from a BAM produced by some other aligner. You will just have to be very methodical when merging these datasets.
