Hey @kedi! You have backslash (\
) characters in your command, these are used to tell your shell that you are escaping the next character in the command. In the case of the QIIME 2 documentation, we use that escaping to allow us to split commands across many lines (so, we are escaping newlines). You have two options:
Split across many lines, with the escaping:
qiime deblur denoise-16S \
--i-demultiplexed-seqs demux-filtered.qza \
--p-trim-length 130 \
--o-representative-sequences rep-seqs.qza \
--o-table table.qza \
--o-stats deblur-stats.qza
Or, make it all one line, without escaping:
qiime deblur denoise-16S --i-demultiplexed-seqs demux-filtered.qza --p-trim-length 130 --o-representative-sequences rep-seqs.qza --o-table table.qza --o-stats deblur-stats.qza
Hope that helps!
