Gb files from the previous version of UGENE couldn't be opened in 1.14.1 and higher. Request from user Allis:
"I have several genbank files with annotations added in previous versions of Ugene, and some of them cannot be opened anymore with the error message:
[18:30:49] 'Load 'some_file.gb'' task failed: The file contains an incorrect data that describes a qualifier value. The value cannot contain a single quote character. The qualifier is ...
When I check the mentioned qualifiers in a text editor, there's no single quote character there.
The bug also affects the latest snapshot ugene-1.15.0-dev-linux-i686-r7499. But does not affect Ugene 1.14.0
I tried version from the ppa as well as ugene-1.14.1-x86-full from the download page."
