taxonomic classification

Good day.

I did an RNAseq, which I assembled by Trinity, then I did a BlastN. BlastN results filtered and organized in a .xlsx file What software can I use to make a taxonomic classification from this file?

A tool like MEGAN can combine the various BLAST hits into hierarchical classification model

https://uni-tuebingen.de/fakultaeten/mathematisch-naturwissenschaftliche-fakultaet/fachbereiche/informatik/lehrstuehle/algorithms-in-bioinformatics/software/megan6/

The result of the BlastN, I have it in this format. BLASTN_NTAgo2021_Trinity_clean_Com06.Trinity.fasta.xml.tab

But the MEGAN6 does not identify it as a BLAST format, Do you know of a way to change it to a format that identifies Megan?

It needs to have certain columns, look up what those are. There are also various other input formats that you may be able to change your data into.
