multiple_join_paired_ends.py error in path

[Riley Hughes]

I am trying to run multiple_join_paired_ends.py but get the following error:

riley@kable-PowerEdge-T630:~$ multiple_join_paired_ends.py -i ~/Documents/Mock_Spike_In/cutadapt_trim -o ~/Documents/Mock_Spike_In/QIIME1/join_paired_ends --read1_indicator '_R1' --read2_indicator '_R2'

The command halts after the first file. I have tried moving fastq_join.py to /usr/local/bin/, making it executable both there and in its original location, (in ./bfillings/), setting the working directory to /usr/local/bin/, adding ./bfillings to PATH but nothing is working. The only thing is when I set the working directory to /usr/local/bin/, I get a slightly different error:

burrito.util.ApplicationNotFoundError: Cannot find fastq-join. Is it installed? Is it in your path?

Any help would be appreciated!
