Hi everyone,
 
I want to calculate GC content of transcripts in the gtf file like this:
 
chr1 Cufflinks transcript 3 22 1000 + . gene_id "CUFF.23955"; transcript_id "CUFF.23955.1"; 
chr1 Cufflinks exon 3 10 1000 + . gene_id "CUFF.23955"; transcript_id "CUFF.23955.1"; exon_number "1"; 
chr1 Cufflinks exon 13 18 1000 + . gene_id "CUFF.23955"; transcript_id "CUFF.23955.1"; exon_number "2"; 
chr1 Cufflinks exon 20 22 1000 + . gene_id "CUFF.23955"; transcript_id "CUFF.23955.1"; exon_number "3"; 
 
and the genome sequence that transcript comes from is:
 
>chr1 
GTAGCGTCTCCGACGCGGATATGACCGCACGCTGATGCTCCCAGGGATGAGAGGCGTGCG 
 
I have to calculate GC content of the transcript after getting the sequence of the transcript.
So how can I get the sequence  of the transcript. In this case, it would be AGCGTCTC + ACGCGG + TAT, meaning 
the transcript sequence would be AGCGTCTCACGCGGTAT. 
 
Is it possible in the Galaxy?
