I am new to qiime2 and have an old workflow from the older version of qiime. I am trying to use the beta-group-significance function. I am using a distance matrix from my old qiime workflow, which is in .txt format. When I run the command the error pops up that the distance matrix txt file is “not a Qiime archive”. I am wondering if Qiime2 requires that distance matrix files are in .qza or .tsv format? If so, is it possible to convert my old distance matrix.txt to the proper format?
Thank you in advance for your help.
