Dear users,
I'm trying to run some of the tutorials provided at http://www.pymvpa.org/tutorial.html, however I'm having trouble importing/accessing the tutorial data. For example, when using: from mvpa2.datasets.sources.native import load_tutorial_data ds = load_tutorial_data(roi=(15, 16, 23, 24, 36, 38, 39, 40, 48)) I get the following error: FileNotFoundError Traceback (most recent call last) <ipython-input-5-aa73ed9c4756> in <module>() 2 from mvpa2.datasets.sources.native import load_tutorial_data 3 datapath = pjoin(cfg.get('location', 'tutorial data', 'haxby2001')) ----> 4 ds = load_tutorial_data(roi=(15, 16, 23, 24, 36, 38, 39, 40, 48)) /home/lyam/anaconda2/lib/python2.7/site-packages/mvpa2/datasets/sources/native.pyc in load_tutorial_data(path, roi, add_fa, flavor) 113 mask = nb.Nifti1Image(tmpmask.astype(int), nimg.affine, nimg.header) 114 elif isinstance(roi, (tuple, list)): --> 115 nimg = nb.load(pathjoin(maskpath, 'hoc.nii.gz')) 116 tmpmask = np.zeros(nimg.shape, dtype='bool') 117 for r in roi: /home/lyam/anaconda2/lib/python2.7/site-packages/nibabel/loadsave.pyc in load(filename, **kwargs) 40 stat_result = os.stat(filename) 41 except OSError: ---> 42 raise FileNotFoundError("No such file or no access: '%s'" % filename) 43 if stat_result.st_size <= 0: 44 raise ImageFileError("Empty file: '%s'" % filename) FileNotFoundError: No such file or no access: './haxby2001/sub001/masks/orig/hoc.nii.gz' Clearly I can't access the data, but beyond that I'm not sure what's going on. Does anybody know what's going wrong here, and/or how to fix the problem? Regards Lyam --------------------------------------------------------- Lyam Bailey, B.Sc., M.Sc.
