introduction to Preprocessing

Four out of five preprocessing methods for FMR projects can be scripted, these are motion correction, slice scan time correction, spatial smoothing and temporal filtering.

 

 

After the creation of the project, it is important for the preprocessing to check whether all properties of the project are set correctly. These are for example the TR, the pixel dimensions and the gap thickness. When the values would not be correct, the preprocessing would cause damage to the data.

Information whether the temporal properties are verified, can be obtained via the document property TimeResolutionVerified. This property can be true or false. When the value is false, the relevant properties can be set in the following way:

 

 

Whether the spatial properties of the project are verified, can be obtained via the project property VoxelResolutionVerified.

To set the values, the following script fragment can be inserted in the script:
