`$seqs =~ /^(>.)>/ms` [download] This will grab everything from the start of the string (assuming the string starts with `>`, upto but not including the last `>`. While technically correct, reading between the lines the OP probably wants to grab the data in chunks that start with `>`. (Otherwise, `substr` would have been a better choice, no?).
