Upload Spectrum

Choose file: covNMR or 2DFT in nmrPipe format

Input Format: covNMR in nmrPipe     2DFT in nmrPipe
(you can use covariance NMR website to generate input file)

Spectrum type: homonuclear     heteronuclear

Method: apply DemixC along w2     apply DemixC along w1

Importance index threshold: e.g. 0.05 (5%)

Trace similarity cutoff: e.g. 0.4 (40%)

Water removal region (in w2): e.g. [4.5,5.0] ppm do not include space

After you click upload button, please wait.
This may take up to 2 minutes to complete for larger datasets.
