TOPSPIN parameters converting the raw data with convdta before you process them. INDEX by 1D, 2D and 3D processing commands which do • also interpreted linear backward prediction, i.e. ft, xfb of tf3 when ME_mod is lpbr INDEX DONE or lpbc. For TDoff > 0, the first TDoff points are replaced by predicted points. For TDoff < 0, abs(TDoff) predicted points are added to the beginning and cut off at the end of the raw data. If zero filling occurs (2*SI > TD), then only zeroes are cut off at the end as long as abs(TDoff) < 2*SI - TD. Note that digitally filtered Avance data start with a group delay. This means that a backward prediction does not make sense unless the data are first converted AMX format with convdta. TM1 - the end of the rising edge of a trapezoidal window • used in 1D, 2D and 3D datasets in all directions • takes a float value between 0.0 and 1.0 • interpreted by tm • TM1 represents a fraction of the acquisition time and must be smaller than TM2 TM2 - the start of the falling edge of a trapezoidal window • used in 1D, 2D and 3D datasets in all directions • takes a float value between 0.0 and 1.0 • interpreted by tm • TM2 represents a fraction of the acquisition time and must be greater than TM1. WDW - FID window multiplication mode • used in 1D, 2D and 3D datasets in all directions • takes one of the values no, em, gm, sine, qsine, trap, user, sinc, qsinc, traf, trafs • interpreted by trf, xfb, xf2, xf1, xtrf*, tf* • On 1D data, window multiplication is usually done with commands like em, gm, sinm etc. which do not interpret WDW. These command P-39
