-The main output of MALT is the `.rma6` file format, which can be only loaded into MEGAN and it's related tools. We provide the `rma2info` text files for improved compatibility with spreadsheet programs and other programmtic data manipulation tools, however this has only limited information compared to the 'binary' RMA6 file format (the `txt` file only contains taxonomic ID and count, whereas RMA6 has taxonomic lineage information).
