I think this is not what I need. I need my cufflink assembled transcripts in Ensemble format or NCBI?
Hi Guys
I used gffread -w transcripts.fa -g /path/to/genome.fa transcripts.gtf
to get my transcripts in fasta format.
What I got is cufflinks ids because this is what is found in cufflinks transcripts.gtf:
>CUFF.1.1 gene=CUFF.1
GTGACTGAACTCTTCACCCCAGTCTGTGGCTTTCCCGTTGCAGTGAGAGCCACGAGCCAAGGTGGGCACT
TGATGTCGGATCTCTTCAACAAGCTGGTCATGAGGCGCAAGGGCATCTCTGGGAAAGGACCTGGGGCTGG
TGAGGGGCCCGGAGGAGCCTTTGCCCGCGTGTCAGACTCCATCCCTCCTCTGCCGCCACCGCAGCAGCCA
CAGGCAGAGGAGGACGAGGACGACTGGGAATCGTAGGGGGCTCCATGACACCTTCCCCCCCAGACCCAGA
How I convert this to something like:
>ENST00000342066.7
CCAGCAGATCCCTGCGGCGTTCGCGAGGGT
or even NCBI codes, fine with me.
I need this to use lncscore to detect some novel lncRNA.
Thanks

Just download the cDNA sequences from from the Ensembl FTP site.
Did you use the -G option and a known reference GTF file with Cufflinks at some point in this process?
No, should I use that?
From cufflinks manual:
-g/–GTF-guide <reference_annotation.(gtf gff)><="" p="">
Tells Cufflinks to use the supplied reference annotation a GFF file to guide RABT assembly. Reference transcripts will be tiled with faux-reads to provide additional information in assembly. Output will include all reference transcripts as well as any novel genes and isoforms that are assembled.
Great, thanks genomax a lot, appreciated :)
