Parameters in shhh.flows


I want to know if there is difference in using the flow= parameter with 8 processors and file= param (with a file containing 1 sample) with 8 processors

I there is difference, which one is faster ?

Thanks in advance

The shhh.flows command divides the work between processors by the number of flow files. If you use the file option, mothur reads the file, counts the number of flow files, and then divides the flow files between the processors. If you use the flow option, then only one processor is used because only one flow file can be given.
