WebIf using QIIME1 to demultiplex paired-end data, we recommend turning off filtering as the QIIME filtering causes the forward/reverse reads to be in mismatched order. You can do this by passing split_libraries_fastq.py the following arguments: -r 999 -n 999 -q 0 -p 0.0001. The QIIME2 platform also supports demultiplexing for the EMP indexing format.
