On Varian VnmrJ with BioPack

Latest versions of Varian BioPack have a few options to include the non-uniform sampling. You need to read the help available from within VnmrJ and follow instructions for Orekhov's procedure. Any BioPack pulse sequence can be modified to include non-uniform sampling. In the end, before processing the data, you should have the modified pulse sequence file (PULSE_SEQUENCE_S.C) as well as a number of additional files, most importantly (PULSE_SEQUENCE_S.HDR_3), where PULSE_SEQUENCE signifies any standard BioPack sequence. Use macro BPSVF to save the data, as regular SVF will omit these necessary files.

From here, the processing follows same logic as that for Bruker data. Home-built software reads the recorded FID, PROCPAR and other relevant files and inserts zeros in the right places, so that the final FID.SP file has the actually recorded FIDs in the order they would be if the 100% of the final spectrum were recorded.
