`wgd viz` throws error when including self-comparison as --speciespair

[taprs]

Hi again! I found a few bugs which are not absolutely prohibitive but would be good to fix at some point. I think I will post them here one by one.

I run substitution rate correction with wgd viz in wgd 2.0.22 as follows:

wgd viz -d wgd_ksd/global_MRBH.tsv.ks.tsv \
    -epk species1_ksd/species1.fa.tsv.ks.tsv -sp speciestree.txt -rw -ap species1_syn/iadhore-out/anchorpoints.txt  \
    -sr "species1.fa;species2.fa" -sr "species1.fa;species3.fa" -sr "species1.fa;species4.fa" -sr "species1.fa;species1.fa" \
    -gs wgd_ksd/gene_species.map --plotkde --plotelmm

and get the following StopIteration output:

14:15:25 INFO     This is wgd v2.0.22                                                                                                               cli.py:32

Removing the -sr "species1.fa;species1.fa" portion of the command results in a successful run. Can you reproduce this?

Hi, could you show me the content of your speciestree.txt?

[taprs]

Here it is:

(zostera:0.261188,((polygonifolius:0.0158094,coloratus:0.0182822)0.806137:0.0266174,(pusillus:0.0230147,(obtusifolius:0.0181003,(trichoides:0.0109874,acutifolius:0.013523)0.386264:0.0102274)0.345251:0.0108846)0.679006:0.0221993)1:0.261188);

I should have thought about matching the tree labels with the input data! Maybe it would be good to have a check for that for people as absent-minded as I. Also I noticed the file did not have a newline in the end.

Yes, the label in your speciestree.txt should match the parameters given by -sr option.

Inputting the correct species tree solved the issue for me.
