To improve the precision of diffusion data using VNMR we frequently
run a diffusion standard before and after unknown samples and fine-tuned
gcal after data acquisition. With VNMR this was easy since gcal is a
"processing" variable and can easily be changed just before the dataset
is processed using DOSY; however with VNMRJ gcal and/or DAC_to_G behave
like "acquisition" variables and revert to the value used during
acquisition even after you change them.
Does anyone know a fix for this?
