How to extract gene expression data from the daa file for a specific taxon

Hello, I am analyzing metatranscriptomics data and have run diamond blastx and daa-meganizer following the Diamond + MEGAN pipeline introduced in Bağcı et al. (2021).
I was wondering if it is possible to use the daa file to obtain gene expression data for a specific taxon (e.g., a class) or use the data file to extract data for a specific taxon and then run MEGAN or daa-meganizer. Any suggestions would much appreciated.

Yes, there is an Extract Dataset menu item in the Files menu. You can select nodes of interest and then extract all info for those nodes into a new file.
