I have been using QIIME2 for some time, and now currently running the 2019.1 version.
In my current project, I will need to merge the results from data2 from three Illumina runs. I have done everything up the merging step. However, upon merging, I realize an identical sample ID was used in two datasets, so getting an error message from QIIME2 saying it was a problem and I would need to fix it. I still want to include both results after merging, so I guess I will have to rename one of them, i.e., sampleX in dataset1, and sampleXRepeat in dataset 2.
Is there any way that I can change the sample ID permanently in the feature table and repset artifacts for this purpose? I searched through the forum, and saw a post about using the meta table and create a column for regrouping. I don’t think this can help with my issue.
Thanks in advance.
