Hi, this is my first time using qiime, the thing is the sequences that were given to me were paired-end fastq files (demultiplexed) so i followed the casava import tutorial.
then i tried to run dada2 to denoise:
qiime dada2 denoise-paired --i-demultiplexed-seqs demux-paired-end.qza --o-table table-try.qza --o-representative-sequences rep-seqa-try.qza --o-denoising-stats denoising-stats-try.qza --p-trunc-len-f 30 --p-trunc-len-r 30 --p-chimera-method consensus --verbose Running external command line application(s). This may print messages to stdout and/or stderr. The command(s) being run are below. These commands cannot be manually re-run as they will depend on temporary files that no longer exist.

i originally tried without specifying the chimera parameter but i received the same error. I think it is an issue in the importing process but i can not be sure
i would really appreciate your help
