Hi,

I just want to find out my RNA-Seq data's type, weather it's Stranded or non-Stranded. I read comments and manual about Salmon, but I don't know HOW? I didn't use Salmon before. So I can’t thank you enough if you help, How can I realize my data's type?

With respect

Run salmon on a few million reads with --libType A and it will make a best guess.

You should understand your data first. Align a subset of your data, then view it via IGV and verify that it behaves the way it should.

The sense/antisense orientation of the reads ought to be immediately clear.

FWIW there is even "software to guess the RNA-Seq library type of paired and single end read files using mapping and gene annotation"

https://github.com/NBISweden/GUESSmyLT

the README for the tool above has a comprehensive tutorial of what the different library types are and how they work
