Hi, folks
I am working hard to practise the RNA-seq data processing with Galaxy.
What confused me a lot is that the raw data of the similar size could give very different accepted hits files in terms of size. What's wrong?
For example one RNA-seq raw data is 4.2G and the accepted hits file is only 8M
the other is 3.9G and the accepted hits file is bigger than 800M!
The data is from from the same cell line but not the same experiment.
Anyone has any idea about this?
