Cuffdiff thread option

[gwilymh]

Can anyone explain to me the following option in CuffDiff:


-p/--num-threads <int>
Use this many threads to align reads. The default is 1.

What are threads? Will it take longer to run the analysis if multiple threads are used? Will such an analysis be more accurate?

These are the individual processes that are used by cuffdiff. For example if you have a hyper-threaded core-i3, use -p 4. It uses as much CPU power as possible. So it shortens the analysis time. If you have a 4-core CPU, you are better off using -p 8. It depends on how many thread your processor can handle.
