How to make a metadata mapping file from indexes only

User Support
1

Hi colleagues
I previously saw few posts on making a metadata or manifest file when you have only sampledID and indexes. Still I have confusion and I am asking it again.

I have 55 Miseq samples as 110 paired end demultiplexed files. I have i7_index, i5_index against each sample ID in an excel file.

I want to make a mapping file for my samples. I am not sure which barcode (eithwe i7 or i5) I should use for samples indexing. May be I have to use both?
Also I am not sure if barcodes or linker primers are still present in the sample sequences. I am attaching barcodes file and 1 fastq file's head here.
I saw that in the previous posts Mehrbod_Estaki mentioned to make a manifest file and move-on. But it will be difficult for me to proceed with manifest file.
My request here is that if someone can help me to make a mapping file from the available information and then I can follow atacama soil tutorial for analysis.

Lastly. If making a manifest file is the best option here then what will be the (1) command for importing data and (2) which tutorial I should use for subsequent analysis.

Index file

Let's take a step back --- are your reads multiplexed, or demultiplexed (per-sample?).

Dear Dr Dillon

My samples are demultiplexed. As I told that I have 110 fastq.qz files for 55 samples.

Cool! So then, as far as QIIME 2 goes, you don't need your barcodes in a metadata file at all, since those would only be used for the purposes of demultiplexing (and as you just showed, that isn't necessary).

Your manifest file (which is different than a metadata file), will reference the files you just shared above, and that is it!

Dear Dr Dillon
I have made manifest file as it is below.
Now I assume I need to run this command to import sequences

qiime tools import
--type 'SampleData[PairedEndSequencesWithQuality]'
--input-path manifest_zubi.cvs
--output-path paired-end-demux.qza
--source-format PairedEndFastqManifestPhred64

Wherein "manifest_zubi.cvs" is my manifest file name
source-format may be "PairedEndFastqManifest" but it still doesnt work

AND This command gives error message "Error: no such option: --source-format"

Great @drmusk!

By the way, I am not a Doctor, myself.

It sounds like you are using docs that don't match your version of QIIME 2 installed - in recent versions of QIIME 2 the parameters in this command have been renamed, in particular, --source-format was renamed to --input-format. If you ever run into a problem like this it helps to run the command with the --help flag to read the latest help text! :qiime2:

Dear Colleague
I used below command to import demultiplexed fastq,qz files. but it gave me error message.

$ qiime tools import --type 'SampleData[PairedEndSequencesWithQuality]' --input-path Zubi_manifest_4.csv --output-path paired-end-demux.qza --input-format PairedEndFastqManifestPhred33
There was a problem importing Zubi_manifest_4.csv:

Zubi_manifest_4.csv is not a(n) PairedEndFastqManifestPhred33 file:

Found header on line 1 with the following labels: ['"sample-id', 'absolute-filepath', 'direction"'], expected: ['sample-id', 'absolute-filepath', 'direction']

I am attaching my manifest file here.
Can you please help me to build this command?
May be I also need to rename --input-format ?

This error suggests that your manifest file has quotes (") at the start and end of each line --- Microsoft Excel sometimes does this when you save. Maybe you can change the settings when saving? Or, copy and paste the contents into a new file.

Thanks for replying
Apparently, it doesn't show if it has quotes over it. But I will try something.
The other thing. Is below input-format script right? Or I should try both Phred33 and Phred64.

--input-format PairedEndFastqManifestPhred33

Dear Mathew
Thanks
It worked.
I actually saved my manifest file as txt file and it worked well.
The output .qza file is exactly of the same size as was my compressed fastq.qz
