Is there a maximum file size (fasta format) that Jalview will accept?
If so, what is it? I cant increase java/virtual memory - no access to
this at my university. So curious to know what the max file size is
for running alignments on the "launch anywhere" downloadable version
of Jalview.
By 'Launch anywhere' I assume you mean the webstart version ? If so,
you can tweak virtual memory settings by creating a custom JNLP file
(http://www.jalview.org/jvmmemoryparams.html).
If you mean the 'InstallAnywhere version' then you may indeed have
problems due to admin rights.
Either way, the largest memory allocation you can set is around 50% of
the physical memory of your machine (e.g. if you have 2G memory, then
you can allocate up to around 1G to Jalview).
Finishing up my co-op and want to know if I can align a HUGE file, (i
dont know what size it would be yet since I have not made it).
Basically looking to make a neigbour joining tree in jalview with
about 15 different species (ranging from 10 sequences for one species
up to about 800 for another). Dont want to waste my time making this
huge file if it wont align/run.
You aren't going to be able to align that many sequences with the public
web services that Jalview talks to, since there is a physical limit of
1000 sequences of up to 1000 residues each. Tree building will probably
take a long time once you've computed that alignment, too, since Jalview
doesn't use any tricks like BioNJ to speed up the tree building process.
Basically, for very large sequence sets, there are a couple of routes,
and all involve downloading and installing additional programs which
have to be configured or run from the command line. Email me directly if
you'd like to discuss your options - since they don't necessarily
involve Jalview ;)
Jim.
