Same Fid Start and Increment

Use the Database Tools > Database Utilities > Same Fid Start and Increment menu option (RESAMPDB GX) to change the fiducial sampling of a database based on a reference channel. This is similar to the REFIDDB GX, but it uses only the fiducial start, increment, and number of samples in the reference channel, not the data values themselves, to compute the fiducials in the resampled database.

If you want to resample the database based on a distance reference channel, and use the distance values themselves to calculate the new FID start and increment, you should use the REFIDDB GX.

Same Fid Start and Increment dialog options

Reference channel

Select the fiducial reference channel. Only the fiducial start, fiducial increment, and number of data values from the reference channel are used; the data values themselves are ignored.

Script Parameter: REFIDDB.REF

Application Notes

The RESAMPDB GX will generate a database where all channels share the same fiducial start and increment. This can be used to eliminate the red bars that indicate channels are not displayed according to their true fiducial indices. To achieve this, data may be interpolated or potentially skipped.

Since this GX has the potential to modify data across the entire database, it’s recommended that you create a backup of your data.
