I am having a problem with my metadata. I ran Keemei and it appeared: 46 invalid cells, 0 errors, 46 warnings. It seems to me that these invalid cells and the warnings refer to the names of the samples that have underscore. I am using qiime2-2019.1 version, is this a problem? Any tips?
Here is the ERROR:
There was an issue with loading the file mapping_feb2020.tsv as metadata:
Metadata file must be encoded as UTF-8 or ASCII. The following error occurred when decoding the file:
‘utf-8’ codec can’t decode byte 0xe7 in position 4033: invalid continuation byte
There may be more errors present in the metadata file. To get a full report, sample / feature metadata files can be validated with Keemei: https://keemei.qiime2.org
Find details on QIIME 2 metadata requirements here: https://docs.qiime2.org/2019.1/tutorials/metadata/
Thanks in advance!
