exception tvb.basic.exceptions.TVBException(message, parent_exception=None)[source]

Bases: Exception

Base class for all TVB exceptions.

exception tvb.basic.exceptions.ValidationException(message, parent_exception=None)[source]

Bases: TVBException

Exception class for problems that occurs during HasTraits validations on fields.

profile

readers

This module contains basic reading mechanism for default DataType fields.

class tvb.basic.readers.FileReader(file_path)[source]

Bases: object

Read one or multiple numpy arrays from a text/bz2 file.

read_array_from_file(file_name, dtype=<class 'numpy.float64'>, skip_rows=0, use_cols=None, matlab_data_name=None)[source]
read_optional_array_from_file(file_name, dtype=<class 'numpy.float64'>, skip_rows=0, use_cols=None, matlab_data_name=None)[source]
tvb.basic.readers.copy_zip_entry_into_temp(source, file_suffix, buffer_size=1048576)[source]

Copy a ZIP Entry into a new file created under system temporary folder.

Parameters:

  • source – ZipEntry

  • file_suffix – String suffix to be added to the temporary file name

  • buffer_size – Buffer size used when copying the file-content

Returns:

the path towards the new file.

tvb.basic.readers.try_get_absolute_path(relative_module, file_suffix)[source]
Parameters:

  • relative_module – python module to be imported. When import of this fails, we will return the file_suffix

  • file_suffix – In case this is already an absolute path, return it immediately, otherwise append it after the module path

Returns:

Try to build an absolute path based on a python module and a file-suffix
