Thanks a lot for the reply.
I ran the first command from this thread.
The command: grep '^>' mcrAtemplate.fasta | tr -d '>' | cat - tax4mcrA.taxonomy | grep -v ';' | sort | uniq -u
But there are many IDs shown!
I do not know the IDs are present in taxonomy file or not! and I do not know I should remove all or not! If yes, there are many IDs, so removing them manually takes much more time.
Could you please give me an idea?
Thanks
