For example, let’s say that you created a mask in FSL, and you would like to extract the data from a statistical map. resample. The fsl module provides classes for interfacing with the FSL command line tools. If not provided, taken from sys. Feel free to use the issue tracker. Thus, if you have the character path of the image or nifti object, these images can be resampled using fsl_resample. resample — fslpy 3. You can specify a desired shape via the New shape inputs, or a desired voxel resolution via the New pixdims inputs. Then we will see how to apply and invert transformations. We will first learn to use the registration tools within the FEAT GUI (graphical user interface of the FEAT program). FLIRT matrices thus encode a transformation from source image FSL coordinates to reference image FSL coordinates. resampleToPixdims(image, newPixdims, **kwargs) [source fslr (version 2.
