Tack så mycket, I will check that website.
The values are the percentage of amino acids in the sequence.
For example, protein A is 100 amino acid long, in which there are 12
arginine, then output for arginine is 12%; for the other 19 amino acids,
it is the same rule.
Thanks anyway,

Hi,
I am quite new to this perl language-I am from biochemistry field.
Now trying to write a script for my current work but could not make it.
The idea is to calculate the composition (percentage) of amino acids in
a protein sequence.
Input is a series of fasta format (protein sequence)
output is a tab delimited format like below:
Name A T C D N Q E .......
protein1 0.23 0.40 0.20 ...
protein2 0.52 0.01 ....
protein3
......
Please go to http://perl-begin.org/ and see if any of the resources there help
you. I'm not initimately familiar with the Fasta format -
http://en.wikipedia.org/wiki/FASTA_format - but what should the output contain
exactly?
Could somebody help me with this? I tried reading some books like perl
for bioinformatics, but still not into it.
Thanks in advance.
Changrong
