Dear Alonna,
If you look at the file `macrel.out.all_orfs.faa` that is generated in the output directory, the sequence headers should allow you to do what you want (if I understood correctly).
There are prodigal headers, so for example
>k77_5_2 # 1984 # 3048 # 1 # ID=2_2;partial=00;start_type=ATG;rbs_motif=TAAAAA;rbs_spacer=7bp;gc_cont=0.487
means contig "k77_5" from positions 1984 to 3048 (in this case, this is not a smORF, but hopefully the point remains).
Best
Luis
PS: This is more a more general mailing-list for the AMPSphere project, but macrel is a part of that (the only part that is so far completed/published)
