Daa2rma stopped at 70%

Hi there,

I am using daa2rma program to convert two paired-end files with each 9062879 reads to single rma file but unfortunately, the program stopped at 70% without completion.

I wonder if this is something to do with the memory or other factors? How can I fix this?

Many thanks

How much memory did you give MEGAN? This appears at the bottom right of the MEGAN main window. Should be 8 G or preferably more. If on MacOS or Linux, edit the megan.vmoptions file in the installation directory to give the program more memory, if necessary.
Please let me know with how much memory you tried running the program. It might be that the new accession database code is using a lot of memory, in which case I will work on fixing that.
