Using PoGo for proteogenomic mapping of 3-frame translated proteome

[nattzy94]

Hi,

I have performed a 3-frame translation of an assembled transcriptome. I have a fasta file containing these sequences with the header containing the transcript id and reading frame followed by the translated sequence with stop codons as asterisks. I have included an example below:

ENST00000456328_(+1)

I have tried using this fasta file as input to PoGo but this fails. Can you advise if it is possible to use PGx to map a 3-frame translated proteome back to the genome and how I may do so?

Thank you!
