Adjust files to be compatible with Mia

[NeginValizadegan]

The "seqtab.txt" file currently output by the TADA pipeline is not directly compatible with the Mia package, which we plan to transition to from Phyloseq.

According to Mia tutorial here:

"Abundance table (assay_taxa.csv): data matrix (features x samples); first column provides feature IDs, the first row provides sample IDs; other values should be numeric (abundances)."

Example:
