Hi Filipe

It sounds like you are better off using the "Frame Line Features..." option.
This allows you to define what features you want displayed on the frame
lines. I think the other option is there for convenience and for when it is
suitable.

In the development version of Artemis you can have GFF3 with multiple
sequences and the coordinates for the features relating to each (as below).
E.g.

## gff-version 3
##
contig1 foo     CDS     3       32      .       -       .
ID=cds1;colour=8
contig1 foo3    CDS     3       32      .       +       .
ID=cds3;colour=8
contig2 foo2    CDS     17      19      .       +       .
ID=cds2;colour=2

##FASTA
>contig1

>contig2
gatcccaactgctcctaccgtcattggatccagcggcgttccctcttccttctccaccgt
tccttctagcagcggcgtcaagagctctaccaagactgcctcgaccgcaactgccaccga


Hope this helps.
