Converting a database to the new 3.1 format

[Olivier Coulon]

Hello there,
I am working with a old database (3.0) and converted it to a new database (using the convert database tool). Then when I use some other BV process, some fields are not filled in because there seem to be a problem with minf files that were generated in the old database, they are not recognised in the 3.1 version. For instance if I take the .minf of a nobias image that was generated under the old hierarchy, it looks like this :

Code: Select all

attributes = {'referential': '1e915515-2e98-46a1-6e83-05b16ab6eec0', 'uuid': '647c2b84-852e-fdf3-599e-03a4ca40d937'}

whereas if I look athe same sort of .minf for another subject that was processed under the new 3.1 hierarchy, it looks like this :

Code: Select all

attributes = {u'volume_dimension': [240, 240, 185, 1], u'data_type': 'S16', u'aux_file': '', u'file_type': 'NIFTI1', u'object_type': 'Volume', u'bits_allocated': 16, u'referentials': ['Scanner-based anatomical coordinates'], u'voxel_size': [1, 1, 1, 1], u'cal_max': 0, u'freq_dim': 0, u'transformations': [[-1, 0, 0, -31.8294, 0, -1, 0, -31.8294, 0, 0, -1, 200.70099999999999, 0, 0, 0, 1]], u'slice_dim': 0, 'uuid': '8e15f15d-a172-6cf3-f95b-379ff9412af9', u'cal_min': 0, u'xyz_units': 0, u'time_units': 0, u'slice_duration': 0, u'storage_to_memory': [-1, 0, 0, 239, 0, -1, 0, 239, 0, 0, -1, 184, 0, 0, 0, 1], u'slice_code': 0, u'referential': '6700fd2a-6eee-8e07-d46f-860ce813be11', u'phase_dim': 0, u'slice_end': 0, u'descrip': '', u'slice_start': 0, u'toffset': 0, u'nifti_type': 1}

Any clue on how I can recover properly my 'old hierarchy' data to a new hierarchy database ?
Thank you.

Hi Olivier,

Most of the fields in the minf file are not used in BrainVISA databases, the most important thing is the full path name(s) of your data. One notable exception is "uuid" but it has no influence on parameter links. I am not sure that your problem is related to minf file. What makes you think so ? Did you try to look at your new database with the database explorer process just to be sure that converted files are recognized in the new structure ?
