Default RNA-seq sequencing depth

Hi everybody,

I've several questions about sequencing depth and RNA-seq. So, what is the minimal read count (in the raw data) to have a good view of :

1. gene expression ?
2. Differential splicing ?
3. Low expressed transcripts (like lncRNA) ?
4. Fusion gene ?

I read that 100M is a minimum for fusion gene ? Is that correct ?
I want to do 2x50bp strand-specific libraires and sequenced them on a HiSeq 2000. Is 50bp enough to find accurately fusion gene ?

Thanks,

N.

50 bp is not enough. You should try 200bp or longer.

Hi guys,

I did 2x100 finally, and it worked pretty well

I'm glad it work out for you Depending on what you are looking for depth is something to consider.

Out of curiosity how did you sequence, i.e. reads/sample?
