Megan is not finding any assignments.
There are two possible issues:
- there could be something wrong with the mapping db file.
Could you please try opening it using the command line program sqlite3 like this:
sqlite3 megan-map-Feb2022-ue.db
and then type:
select * from info;
.quit
Does that work?
If it does, then the question is
(2) which database did you align against? Which mapping db file are you using (e.g. megan-map-Feb2022-ue.db?). If there is a mismatch between the database against which you aligned the sequences and the mapping db file that you are using, then this would explain why there are 0 assignments.
