I have two transctipts.gtf files which are outputs of cufflinks. One is 69.4 Mb and the other one is 38 Mb.
When I merge these files with their annotation file the merged.gtf file is 75 Mb. Why it is small in size? (69.4 + 38 = 107.4), so I mean the minimum size of merged file should be 107.4. Isn't it?
