[DESCRIPTION]
This is a protocol for running the Bruker pulse program "hsqcetgpsisp2".

[BEFORE_START]
This protocol assumes:
Your sample is loaded, locked, tuned for both proton and carbon channels, and shimmed in the magnet
The calibrated 90° pulse value for proton (i.e., P1) for the sample has been collected

[GUIDELINES]
This protocol intends to provide concise instructions to carry out the experiment. For more comprehensive information, see Bruker's documentation "Basic NMR Experiments" by clicking ? →  Manuals (docs) on the menu bar on TopSpin. See also "Pulse Program Catalogue. 1D/2D" for the details about the pulse program used in this protocol.

[STEPS]
SECTION: Create a new dataset

SECTION: Create a new dataset
1.4. A new window opens. On the right top bar, select
Source = /opt/NAN_METAB/par
 
In the list, select the one you want to use:

For serum and plasma samples:
HSQC_br600_serum.par: Parameter set using an acquisition mode "traditional planes"
HSQC_NUS_br600_serum.par: Parameter set using an acquisition mode "non-uniform sampling (NUS)". Higher resolution on the indirect dimension

For urine samples:
HSQC_br600_urine.par: Parameter set using an acquisition mode "traditional planes"
HSQC_NUS_br600_urine.par: Parameter set using an acquisition mode "non-uniform sampling (NUS)". Higher resolution on the indirect dimension
