    ie. for the left string I have tried trick like:
    if ($string =~ m/([ACTG]+).*[actg]/) {
    print $1
    }
    and several other variations but all I get is an uppercase string till the first character other than ACTG.
      #!/usr/bin/perl -- use strict; use warnings; use Data::Dump; $_ = 'G_I1E2_GTGGAG^303CTGgacgCCCTGC_I2E3_TACA'; my @matches = ""; while( m{ ([ACTG]+)# $1 is upper | ([actg]+) # $2 is lower }gxsm ){ if( $1 ){ $matches[-1] .= $1; } if( $2 ){ push @matches, ""; } } dd \@matches; __END__ ["GGTGGAGCTG", "CCCTGCTACA"]
