Loading and Saving Data

File Formats

This software package works with NIFTI volumes. Some builds may contain experimental support for folders of DICOM files, however this is not well tested.

Alternative packages which are able to convert DICOM files to NIFTI include the following:

Loading data

Drag and drop

You can drag and drop single or multiple files onto the main window to load data. You will be prompted to choose the type of data:

The suggested name is derived from the file name but is modified to ensure that it is a valid name (data names must be valid Python variable names) and does not clash with any existing data.

If you choose a name which is the same as an existing data set, you will be asked if you wish to overwrite the existing data.

When dropping multiple files you will be asked to choose the type of each one. If you select cancel the data file will not be loaded.

Saving Data

The following menu options are used for saving data:

  • File -> Save current data
  • File -> Save current ROI

So, to save a data set you need to make it the current data, using the Overlay menu or the Volumes widget. Similarly to save an ROI you need to make it the current ROI. Saving the main data can be done by selecting it as the current overlay.
