I encountered the same error in daa-meganizer also?

And I have a query.I want to analyze illumina soil metagenomics paierd sample. I have downloaded
megan-map-Jan2021.db.zip
megan-nucl-Jan2021.db.zip
both these files .which one should I use and why not the other one ?

This seems to indicate that there might be a problem with the disk that you are using:

Is there enough free space and is the .db file read-writeable?

Use megan-map-Jan2021.db.zip for alignments against a protein reference database and megan-nucl-Jan2021.db.zip for alignment against a DNA reference database.
