I would like to filter out some sequences from a fasta file by using a specific pattern.
for example I have this file:
I know already how I can extract all the fasta sequences with a specific pattern into a new file by using awk.
But what I would like to do is to remove all entries of a specific pattern from the original fasta file and save the newly made file into a new one. In my file above, I would like for example to remove all sequences with the header pattern out. and save only the other to a new file.
Is there a tool somewhere for doing that, or is it possible in awk/sed or even grep
