Handling of lower-case protein sequences

[kazumaxneo]

I am trying to visualize the MSA of genes that are coding in two separate positons. I would be happy if I could display the amino acid sequence of one part in lowercase letters. When I tried, I got the following error $ Sequence lengths differ for output format 'mview' - aborting

I use MSA files like this one.
