I have a fasta file with 2000 sequences (big.fasta) with transcripts.
I also have a text file with 70 sequence ids (ids.txt) present between those 2000 sequences.
I want to remove the sequences in ids.txt from the big.fasta file; thus creating a fasta file with 1930 sequences free of the ids from ids.txt.
Also, if possible can I cut and paste those 70 sequences from the 2000 sequences file to some other fasta file?
I am a novice with no prior experience in these matters. Kindly help.
