COLMAR Tocsy query

STEP1, spectrum processing:

(Notice: spectra files can be nmrpipe (.ft2), sparky (.ucsf), Topspin ASCII format (.txt)) or Mnova (.csv) format. The server use file extension to distinguish file format

STEP2: Peak picking and peak fitting
Choose peak picking method

Peak fitting is recommended only if compound quantification is planed.
Choose peak line shape in peak fitting

STEP3(optional): Spectral referencing
The server can calculates the reference correction by matching the peaks patterns of selected known compounds against experimental peaks automatically. Please first choose solvent type, followed by referencing compounds.
Choose solvent type

Choose compounds as references:

STEP4 Database query and match:
