To do this properly you need to follow this basic pattern of steps regardless of the project.
- Create a protein database that you can also generate a
gff
coordinate file for. - Run proteomic searches on this db to create a
protXML
file - Use the
Proteomics to GFF
tool to map proteomics results back to your genomic coordinates.
Step 1: Import your transcriptome (as nucleic acid sequences)
Step 2: Use the Generate 6 frame translation
tool to create a protein fasta file from your transcriptome
Step 3: Use the Generate 6 frame translation
again but specify the gff output option to generate corresponding gff
coordinates
Step 4: Run proteomics searches using the protein fasta file
Step 5: Combine results with the Proteomics to GFF
tool
