Because of this error I stuck with my analysis. It will be more helpful for me, if you help me to solve this issue.

hello everyone, I am Samia.
I am using QIIME1 and did all following steps before the alpha diversity.
But getting one error in the following stepalpha_rarefaction.py -i otus/otu_table.biom -m map_fluid_1.txt -o alpha_fluid_1 -p alpha_params.txt -t otus/rep_set.tre
My purpose is to get the OTU_table_Description.txt, sees_rep_set.fasta, taxa summary and PCoA.
I have tried many ways but cannot solve this problem in this step.
Please, help me.
