Tutorial and example dataset

Your data file:

The uploaded file must be tab-devided text file and its format should be as same as below (blank data cells are allowed).

IDSample1Sample2...SampleN
12345data11data12...data1N
123456data21data22...data2N
54321data31data32...data3N
...

Please give a descriptive name to your dataset (need to be complex enough and better include date and initials of your username, e.g. USERA20220414DataA1. Use only letters or letters plus numbers. Do not include any symbols, e.g. #*,!.;:")

Attention:
(1) The upload file size could not exceed 30Mb.
(2) Currently we can not support Mac generated text file. Please switch to Windows or Linux system to generate your text file.
(3) DO NOT use pure number (e.g. 10) as dataset name.
(4) Do Not use any blank space or symbols or begin with number in your sample name, taxa name (e.g. OTU ID), or dataset name. Better only letters or letters plus numbers.
(5) Leave all "zero" (undetectable) cells as blank (empty) cells. Do NOT include any space in the empty cells. Please remove ghost taxa (e.g. OTUs) which are not detected in any sample, unless you have strong rationale to keep them.
(6) Make the minimum observed value close to but no less than 1. Negative value is not allowed. Do some transformation which would not change correlation coefficient, e.g. multiply the whole matrix by a constant.

Reason and Solution for "500 error":
(1) Address: ensure you are using http://ieg4.rccc.ou.edu/mena/ instead of the old address http://129.15.40.240/mena/.
(2) Browser: test an example dataset from Tutorial and example dataset. If it does not work, it is usually browser compatibility issue. Please try 360 browser, if Firefox, Chrome, or IE does not work. Some users solved the problem by changing to another computer. We feel sorry that Mac can be incompatible now.
(3) Format: if the example dataset works but yours failed, it is usually format issue. Please carefully read the "Attention" above and check your file.

If it still doesn't work, please feel free to contact the maintainers (ningdaliang@ou.edu). Please include your username, email, and dataset name (experiment name) in your email.
