Hello, You can use the tool "Fetch Sequences -> Extract Genomic DNA" with a GTF file and a custom reference genome to get the fasta sequence. Instructions are here for Custom Genomes in general and "Tools on the Main Server" covers this tool: http://wiki.galaxyproject.org/Support#Custom_reference_genome The tool "EMBOSS -> geecee" can be used to perform the calculation on the resulting fasta sequences.

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
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: the transcript sequence would be AGCGTCTCACGCGGTAT. Is it possible in the Galaxy?
