What are the argument to run your script to process, for example, the input file with 6 sequences? I have tried
Code:
 ./script inputfile.fasta 2

but did not get the expected three files with 2 sequences each. Thanks!

Hi.

The demonstration script assumes groups of 2, it is not generalized. You would need to change the split command or modify the script to accept another parameter in addition to the input file name to obtain a different number of sequences in the final set of files.

However, the script as it stands will accept (but ignore) parameters beyond the file name. For example, we can copy the default input file file name, data1, to another file, my-input-test, and run that:
Code:
% cp data1 my-input-test
% ./s1 my-input-test 324

producing the output:
Code:
% ./s1 my-input-test 324

Environment: LC_ALL = C, LANG = C

awk GNU Awk 3.1.5

 Input data file my-input-test:

 Sample: file xab expanded:
>seq3

agtcagtcagtcagtc

Best wishes ... cheers, drl
