Bug in annotation file parser

Jalview Discussion
1

Dear Jalview developers,

Thank you for programming this tool. I am not familiar with the
formalities of your bug reporting system, but I still want you to inform
about this issue.

There seems to be strange bug, if NO_GRAPH" secondary structure
annotations are parsed from an annotation file: If there is a lower case
representation of the used
secondary structure symbol ("H" or "E") present in the text label, the
visual result is an arrow that shows to left. Example...

H,phosphorylation site|

...results in a left directed arrow, while...

H,pxospxorylation site|

results in a bar.

If |E,phosphorylation site| and |E,phosphorylation sitx| are used, this
results in a left and right directed arrow, respectively. If three fields
are used, it is the third field (text label) that matters: |E,phosphorylation
site,phosphorylation sitx| results in right directed arrow, while

E,phosphorylation site,phosphorylation site| in a left directed one.

I use InstallAnywhere,Linux version that I downloaded a few days ago.

A little example is attached.

Best regards
Arne

Hello Arne,

Thanks for reporting this and providing such a clear example.

It does look like a bug, whose root cause is that the code is trying to interpret the display text of the annotation as if it were 'e' as in RNA secondary structure (E-e) base pair notation. (The bug also occurs with sequences that are unambiguously protein residues.)

I have raised a bug report for this
http://issues.jalview.org/browse/JAL-1813
and we'll fix it at the earliest opportunity.

Thanks and best regards,

Mungo
