TOCSY query

STEP1, spectrum processing and peak picking:

Your name and institute*
TOCSY spectrum file
(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!
Optional AMS TOCSY peak file

STEP2, referencing
Automatic by pattern matchings
DSS Alanine Leucine Glucose Lactic Acid
When doing auto-referencing, matching at least
out of known peaks.
1st: 2nd:

STEP3, database query and match:
1H chemical shift cutoff (ppm): , Matching ratio cutoff  
Clique based matching only options:
Peak alightment match cutoff(ppm):
Symmetric_cutoff Peak match cutoff(ppm):

Direct matching max clique matching
data for database query and display.
