Processing varian 2D data done with a 3D pulse sequence

Hello all,I am working with a varian spectrometer and did a 2D experiment with a 3D pulse sequence and I need help with the conversion as well as the processing script with NMRpipe.

In slightly more detail,the pulse sequence is for a C1-N2-C3 correlation, assuming C1 being the first indirect dimension, C3 being the direct dimension.

When I do a N2-C3 correlation, processing with NMR pipe was straighforward(the interface reads it correctly). However I did a C1-C3 correlation and this is my problem. And auto-read parametersresults in a 1D, and I tried manually entering the 2 other dimensions and my scripts looks as follows:

#!/opt/scisoft64/bin/cshvar2pipe -in ./fid \ -noaswap \ -xN 2084 -yN 1 -zN 40 \ -xT 1042 -yT 1 -zT 20 \ -xMODE Complex -yMODE Complex -zMODE Complex \ -xSW 104166.667 -ySW 3200.000 -zSW 5027.020 \ -xOBS 201.134 -yOBS 201.134 -zOBS 201.134 \ -xCAR 54.000 -yCAR 120.000 -zCAR 54.000 \ -xLAB C13x -yLAB N15y -zLAB C13 \ -ndim 3 -aq2D States \ -out ./data/test%03d.fid -verb -ov************************************Upon running this script though there is an error and the following is the output (note the error at the end)

Varian Format: Short Floating-Point Complex Data, 4 Bytes per Point.Varian Sizes: 2084 Total Points per FID, 40 FIDs, 1 Experiment.Varian Four-Byte Float Format --> NMRPipe Conversion.Input File: ./fidOutput Template: ./data/test%03d.fid3D Sizes: (2084 Real+Imag)(1 Real+Imag)(40 Real+Imag)Segmentation faultDoes anyone have experience with this and knows the solution for this? If yes, could you please share it here.

Thanks in advance.PBjang
