Hi, I've been using VBM12:Segmentation, which worked fine before, but now it gives an error. I was wondering whether something has changed in the code since the last update? Specifically, in the step segmentation, modulated normalized, you can choose between 1) affine and non-linear (produces mwp* images) and 2) non-linear only (produces mw0* images). If you choose non-liner only, it works fine, but if you choose affine&non-linear it gives the error shown below. It seems that the function vbm_io_writenii skips defining 'wr' when the option is set to 1? Hope you can help out, Best Marieke ------------------------------------------------------------------------ Running job #1 ------------------------------------------------------------------------ Running 'VBM12: Segmentation' ------------------------------------------------------------------------ VBM12 r684: ./VBM/T1_sub001.nii,1 ------------------------------------------------------------------------ NLM-Filter: 290s Affine Registration: 126s SPM-Preprocessing 1: 226s SPM-Preprocessing 2: 186s Global Intensity Correction: 61s NLM-Filter after Global Intensity Correction (ORNLMstr=0.03): 24s Local Adaptive Segmentation (LASstr=0.50): 174s ROI Segmentation (Partitioning): 107s Blood Vessel Correction (BVCstr=0.50): 5s Skull-stripping using graph-cut (gcutstr=0.50): 34s Amap without Kmeans with MRF-Filterstrength 0.15: 29s Final cleanup (gcutstr=0.50): 25s Dartel normalization: 480s Write result maps: ------------------------------------------------------------------------ VBM Preprocessing error: MATLAB:UndefinedFunction: ./VBM/T1_sub001.nii,1 ------------------------------------------------------------------------ Undefined function or variable "wr". ------------------------------------------------------------------------ 259 - vbm_io_writenii 1407 - cg_vbm_write 326 - cg_vbm_run_job 10 - cg_vbm_run_newcatch 162 - run_job 121 - cg_vbm_run 29 - cfg_run_cm 1673 - local_runcj 953 - cfg_util 707 - MenuFileRun_Callback 96 - gui_mainfcn 53 - cfg_ui ------------------------------------------------------------------------ Done 'VBM12: Segmentation' Done
