Greetings
I am new to all this. I have a fastq files containing multiplexed single-end reads obtained from an Ion torrent PGM machine. I also have a metadata txt file that seems to match the format requirements for using qiime2. My goal is to make OTU level analysis once the data is demultiplexed and cleaned.
However I have been incapable of importing the data.
After looking the moving pictures tutorial (and also checking that it ran in my computer) and reading several forums, I haven't been able to even import the files. The last command I used was:
qiime demux emp-single
--i-seqs Manifest1.txt
--m-barcodes-file DATOS_OTUS/chip1_mp_corrected.txt
--m-barcodes-column BarcodeSequence
--o-per-sample-sequences demux1.qza
--o-error-correction-details demux1-details.qza
The error that showed this time is this:
(1/1) Invalid value for "--i-seqs": 'Manifest1.txt' is not a QIIME 2 Artifact
(.qza)
If I first try to import the manifest file with qiime import:
qiime tools import \
--type 'SampleData[SequenceWithQuality]' \
--input-path Manifest1.txt \
--output-path ION1-mux.qza \
--input-format SingleEndFastqManifestPhred33V2
this error appears:
An unexpected error has occurred:
Semantic type SampleData[SequenceWithQuality] does not have a compatible directory format.
See above for debug info.
Im not sure what I must do and I ran out of ideas.
Any help?
