Re^4: Parsing csv without changing dimension of original file

Thank you very much for your comment. Sorry for the inconvenience. Using "sep=\t" in your first script solved the problem and this give me the exact output as the latest script

my %dict = map { chomp; split '\t', $_, 2 } <$fh>;

I have another problem. In the result, I still have previous text in many cells. Its strange, some cells replaced exactly some not. Either they might not be replaced or replaced by the 1st column of the 'egg_pathway_title.txt'. I was trying to delete those strings but failed. What I have done

ut -f1 bioDBnet_db2db_KEGG_Title_final.txt > exclude-these.txt

but failed. I have tried in many ways. Is there any way to upload my files here? Best Regards Zillur
