Hi

I have two `transcripts.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?
<p>did you merge them with cufflinks? if so, the transcripts that are common to both files will be present only once in the merged.gtf. that&#39;s what merging is for. also, counting the number of transcripts is more informative than looking at the size.</p>
