NAME
getprosol - Get probehead and solvent dependent parameters
DESCRIPTION
The command getprosol reads the probehead and solvent dependent parameters (the prosol parameters) and copies them to the corresponding acquisition parameters. Entering getprosol on the command line is equivalent to clicking the AcquPars tab and then clicking the button. The relations between the prosol and acquisition parameters are shown in table 7.1. These are the default relations which apply to most standard high resolution experiments. Protein, DNA/RNA and LC-NMR experiments require different relations which are defined in the files, triple, triple_na and lcnmr, respectively (see INPUT FILES). To use relations other then default, the so called relations file must be specified in the pulse program. You can do that by editing the pulse program (with edpul or edcpul) and adding the line:
prosol relations=<filename>
before the actual pulse sequence. To look at an example, you can enter edpul lc2 or edpul zgesgp. Note that the file default, for default relations can, but does not need to be specified in the pulse program.
Usage of getprosol with command line options
The command getprosol (get probehead and solvent dependent parameters from the edprosol table) can be called with three options:
•
•
•
the nucleus
P90, the value for 90° hard pulse length
PL90, the value for 90°hard pulse power level
The existing prosol parameterset, set up by edprosol, is not modified.
getprosol Nuc P90 PL90 recalculates standard hard power levels with:
PLx = 20*log (Px/P90) and the standard soft power levels PLSH1 - PLSH16 by:
PLSHx = 20*log (integFac*Px/totRot * (P90/90.0) where integFac (=SHAPE_INTEGFAC) and totRot (SHAPE_TOTROT) are read from the shapes <TOPSPINHOME>/exp/stan/nmr/lists/wave/PNSHx and
<TOPSPINHOMME>/exp/stan/nmr/lists/wave/Gaus1.100 (e.g.)
