It works for me; my question is: it seems not possible to put other sequence information in the manifest file, or it cannot be imported. However, those info (like sample time, type, location ) that categorizes samples are very important for downstream analyses, is it possible to put extra info into the manifest file?
That is correct - a manifest file is not the same thing as a metadata file, so we wouldn't want to put these kinds of data in a sequence manifest!
Have you had a chance to look at the Metadata Tutorial on the docs? Metadata is a first-class citizen in Q2-ville --- it is front-and-center in many QIIME 2 Methods and Visualizers --- just take a look at the Moving Pictures tutorial for a handful of great examples!
