Something that normally works in Jalview has stopped working! What should I do?

Thank you to everyone who wrote letters of support last year for our application to the BBSRC, we should hear the outcome in the next couple of months.

We are now applying to the Wellcome Trust to renew funding to support Jalview's use in biomedical sequence analysis, including interpretation of genomic variation and long read RNA data (e.g. Nanopore) at the protein coding level. If you would like Jalview to continue to develop and be supported then please take a few minutes to write us a support letter saying how you use Jalview in your research/teaching.

Write as a PDF including your institution's heading and send to: by Friday 22nd March 2019.

Thank you!

One of the commonest causes of 'strange behaviour' that our users have reported seems to be Jalview running out of memory. Memory errors can cause some operations to fail silently - with no warning, annotations may disappear from the alignment window, and web service calculations (apparently) never finish.

You should be able to see something in the error log - see the instructions for bug reporting on how to view this. If you do see 'Out of memory' or 'Cannot allocate stack' or 'HeapAllocationError' type messages, then you might be able to fix it by increasing the memory available to jalview.
