invalid 'row.names' length

[silvtal]

Hi, I'm trying to use your web server on my OTU table but I can't seem to upload the dataset. I'm trying to upload an OTU table and a metadata file in .tab format but a "invalid 'row.names' length" pop-up appears whatever I do. It's probably me who's making some silly mistake but I just don't see it

To Reproduce

1. Prepare .tab files trying to imitate the testdata. They look like this:

SampleID    Testvalue
eB1 3
eB2 10
eB3 8
eB4 1
eB7 22

eB1 eB2 eB3 eB4 eB7 eB8 eB9 eF7 eE5 eF4 eE1 eE7 eF6 eG3 eG6 eE8 eA1 eA4 eA5 eA6 eH3 eE2 eE6 eF3 eH7 eA3 eA7 eC2 eC6 eF2 eF5 eF8 eG1 eG4 eG7 eH5 eF1 eB6 eC5 eC1 taxonomy
4371191 3   10  8   1   22  7   16  12  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   k__Bacteria;p__Proteobacteria;c__Gammaproteobacteria;o__Pseudomonadales;f__Pseudomonadaceae;g__Pseudomonas;s__

2. Go to "Upload your OTU/ASV table" at https://exbio.wzw.tum.de/namco/
3. Add both files and press "Upload" button

I've tried adding and removing a header, removing and adding the first column's header, adding a phylogenetic tree, adding quotes... Nothing

Expected behavior No error should pop up

Screenshots

Desktop (please complete the following information):

• OS: I've tried editing the files from both Windows 10 and Ubuntu 21.10
• Browser: Firefox

Hi,

I just used the few lines of your OTU table as input and it worked for me: otu.txt meta.txt

Do they work for you as well?

Could you maybe share the complete OTU and meta tables? Can also be via email if its sensitive information (alex.dietrich@tum.de).

Best, Alex

Sent, thank you. It looks like it's 40 samples in both files, I don't get it...

I forgot to add: yes, those short files you uploaded do work for me too

Hi,

So i found your error: it seems like there are a few rows in your OTU table where you do not have all taxonomic levels defined. I will adapt the error message to make this more clear and update Namco.

[silvtal]

I see. I added the missing fields and also a "OTU" column name for the first column and now it works as expected. I should note that it was not necessary to remove spaces nor characters such as [, ] or -.

Thank you so much for the quick response and update!!

[alex-d13]

Great that it works now :)
