TOCSY query

Visit a step by step how-to with figures here

STEP1, spectrum processing:

Your name and institute*
TOCSY spectrum file
Optional HSQC spectrum file
Optional user chosen session name
(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 fitting
Minimal amplitude Water line width in ppm
Include shoulder peaks?
Download picked peak list file.

STEP3, referencing
Referencing compounds selection: aqueous or organic.
DSS Alanine Leucine Glucose Lactic Acid

When doing auto-referencing, matching at least
out of known peaks.
Automatic by pattern matchings
1st: 2nd:
STEP4, database query and match:
1H chemical shift cutoff (ppm): , Matching ratio cutoff  
Clique based matching only options:
Peak alightment match cutoff : ppm, Symmetric peak match cutoff: ppm, Skip peaks within ppm of diagonal

Direct matching max clique matching

Estimated noise level of TOCSY spectrum is
TOCSY Lowest contour level: = 0

Control: Brush an area to Zoom in, or remove peaks within this area. , ,
