Since XWINNMR 3.0, the program offers new probehead and solvent dependant prosol handlingThe commands and replace the previous commands solvloop, liprosol, gpro and prosol together with the internal hand-ling of the pulsesort procedure to copy symbolic pulse variables to the actual acquisition parameters.
The command displays a table of probehead and solvent dependent parameters such as pulse widths and power levels. The scope of this table has been extended compared to previous XWIN-NMR versions to accommodate a larger number of parameters for different applications and for all accessible nuclei.
The command can be used to copy the pulse table to the current data set, taking into account the spectrometer hardware setup and the respective pulse program. The pulse widths and power levels are copied according to internal relation files describing the assignment of symbolic pulses to the pulses and power levels used by TOPSPIN.
So far, for three different NMR applications three relation files are provided with TOPSPIN : "default", "lcnmr" and "triple". The "default" relation file contains all parameter mappings needed for standard applications and is always evaluated when nothing else is specified in the pulse program. The "lcnmr" relation file is used by LC-NMR pulse programs, whereas the "triple" relation file contains additional mappings for biomolecular NMR experiments. The relation files reside in the directory:
TOPSPINHOME/conf/instr/ and can be specified in the pulse program with the statement/prosol/relations /* relations "relationfilename" */ on a single line before the beginning of the actual pulse sequence.
