Hi All, I am trying to concatenate several hundred files based on their filename.. Filenames are like this:
Q1.HOMOblast.fasta Q1.mus.blast.fasta Q1.query.fasta Q2.HOMOblast.fasta Q2.mus.blast.fasta Q2.query.fasta ... Q1223.HOMOblast.fasta Q1223.mus.blast.fasta Q1223.query.fasta All the Q1's should be concatenated together in a single file = Q1.concat.fasta.. Q2's go together, Q3's and so on... I envision something like for file in os.listdir("/home/matthew/Desktop/pero.ngs/fasta/final/"): if file.startswith("Q%i"): concatenate... But I can't figure out how to iterate this process over Q-numbers 1-1223 Any help appreciate. -- http://mail.python.org/mailman/listinfo/python-list
