Hello, Perl Monks;

I have a multi fasta file (with header > and sequence) in the following format:

>contig_1 # 498 # 1826 # 1 # ID=1_1;partial=00;start_type=ATG;rbs_motif=AGxAGG/AGGxGG;rbs_spacer=5-10bp;gc_cont=0.406

MNLTFDYTKEPSRDVLCIDVKSFYASVECVERG LDPLKTMLVVMSNSENSGGLVLAASPM

>contig_2 # 1823 # 2173 # 1 # ID=1_2;partial=00;start_type=ATG;rbs_motif=GGA/GAG/AGG;rbs_spacer=5-10bp;gc_cont=0.311

MKQNRKEFSSYFSRSIKQNKPLYLLLMSSETNPF PRPVIGTFRGYVEENKIIIGEDSYSI

.... ...

and i want to edit the header lines as just a simple number count:

>1

MNLTFDYTKEPSRDVLCIDVKSFYASVECVERG LDPLKTMLVVMSNSENSGGLVLAASPM

>2

MKQNRKEFSSYFSRSIKQNKPLYLLLMSSETNPF PRPVIGTFRGYVEENKIIIGEDSYSI

.... ...

may be it's a too simple questions, but I only started to learn perl and got stuck..

thanks in advance..
