Unable to Download Mapping Files

Hi

I’m facing issues with downloading the following mapping files from the MEGAN6 download page

gi2seed-May2015X.bin.zip
nucl_acc2tax-Aug2016.abin.zip
acc2eggnog-June2016X.abin.zip

Further, is the nucl_gi2tax mapping file the extended one?

Thanks,
Aditya

Dear Aditya,

I can’t reproduce the problem that you are having with the three named files. What is the problem that you have? File not found?

nucl_acc2tax-Aug2016.abin.zip is not an “extended file”. It is based only on the mapping of accessions to taxa provided by NCBI.

Dear Daniel

For nucl_acc2tax-Aug2016.abin.zip, the file downloaded after several tries. But when I try unzipping the file on my server, it says

Archive: ./MEGAN_Ultimate_Mapping_Files/nucl_acc2tax-Aug2016.abin.zip

As for the SEED mapping file, the file just fails to download after several tries

Looks like there is a problem in downloading complete files. I am not sure what is causing that. The problem with the acc mapping files is that they are very big, even compressed. I will look into using a different technique to model acc mapping files in the future. Please try again and if there is still a problem I can put them on Dropbox for you.
