Hi all,

I am currently using MEGAN for my soil metagenomics. After using the latest version DIAMOND to get the DAA files, I imported these files to MEGAN along with GI mapping files (GI-Taxo, GI-KEGG, GI-SEED) downloaded from MEGAN6 website. The results show none of my sequences can be assigned to any function or taxonomy. Otherwise, the software said that my DAA files from DIAMOND are not DAA files. Did anyone face this kind of situation before?

Thank you, Dave

the daa format has been a moving target in the past - maybe the latest version is incompatible with megan6. Did you try to convert the daa with the meganizer tool?

I had a similar case I think. Have a look here:

I already tried meganizer tool but it said Daa is not Daa file. Yesterday, I found out that the Daa file I got from DIAMOND is not actually DAA file because I used -o output.daa instead of -a output.daa. It's OK now but the number of sequences assigned to SEED is too low. It might because of my sequences or something else happened. Thank you guys.
