I’m beginning to work with Osprey and am encountering an issue while processing Siemens MEGA-PRESS data in TWIX format (3T, Vida, syngo XA31, Siemens MEGAPRESS product sequence ‘svs_edit’, TR/TE = 3000/68, GABA editing at 1.9ppm, 96 edit-off and 96 edit-on single scans, 4096 fid points). After loading the TWIX file, Osprey processing fails with an error message:
Error using op_phaseCrCho (line 37)
ERROR: Can not operate on data with extras dimension! ABORTING!!
Error in op_measureDrift (line 46)
[in,~] = op_phaseCrCho(in, 1);
Error in op_robustSpecReg (line 63)
driftPre = op_measureDrift(in);
Error in OspreyProcess (line 258)
[raw, fs, phs, weights, driftPre, driftPost] = op_robustSpecReg(raw, seq,
0,refShift_ind_ini); % Align and average
Error in OspreyPipe_20240518 (line 10)
MRScont = OspreyProcess(MRScont);
It appears that Osprey is having trouble assigning the edit-on/edit-off data dimensions in the TWIX file. For reference, please check the example TWIX file, my Osprey Job File, Osprey loading output, and my Osprey Pipeline at this link: UKH Cloud (password: jwfHmzZS).
Thanks in advance for helping me!
