This matrix is not altered by Facelift. The person executing facelift, however, should have write permission on this matrix. Name of the matrix which will contain the output basepoint corrected data. This matrix is created by Facelift. Dimension number along which basepoint correction is to be made.
Facelift performs basepoint correction one dimension at a time.
Lower values for this parameter will result in more signals being removed from the spectrum. Conversely, higher values for this parameter allow only broader signals to be removed from the spectrum. A reasonable range of values for this parameter is 16 to 128 data points. The execution time of the program is linearily proportional to the value of this parameter. A lower value for this parameter means that weaker signals will be retained by Facelift.
