Added

3.6.3 (Wednesday 28th July 2021)

Changed

  • The fslpy API ocumentation is now hosted at https://open.win.ox.ac.uk/pages/fsl/fslpy (!290).

  • The fsl and fsl.scripts packages have been changed from being pkgutil-style namespace packages to now being native namespace packages (!290).

  • The TaskThread now allows an error handler function to be specified, which is run on the idle loop (!283).

Fixed

  • Fixed an edge-case in the gifti module, where a surface with a single triangle was being loaded incorrectly (!288).

  • Fixed an issue in the func_to_cmd() function, where it was unintentionally leaving flie handles open (!291).

3.5.3 (Tuesday 9th February 2021)

Fixed

3.5.2 (Friday 29th January 2021)

3.3.2 (Tuesday 12th October 2020)

Changed

  • Most wrapper() functions now accept an argument called cmdonly which, if True, will cause the generated command-line call to be returned, instead of executed.

  • New vest.loadVestFile() and vest.generateVest() functions.

Changed

  • Updates to the BIDS filetree specification.

Fixed

Changed

  • The fslsub.func_to_cmd() function allows more fine-grained control over whether the script file is removed after the job has finished running.

3.2.1 (Tuesday 23rd June 2020)

Changed

  • Minor updates to documentation.

3.2.0 (Thursday 11th June 2020)

Added

  • A new fslsub.hold() function to wait on previously submitted jobs, to be used in place of the wait function.

3.1.0 (Thursday 21st May 2020)

Added

  • New cifti module, providing classes and functions for working with CIFTI data.

  • New winpath() and wslpath() functions for working with paths when using FSL in a Windows Subsystem for Linux (WSL) environment.

Changed

  • Image() objects created from numpy arrays will be NIFTI1 or NIFTI2, depending on the value of the $FSLOUTPUTTYPE environment variable.

Fixed

  • Updated the fast() wrapper to support some single-character command-line flags.

3.0.1 (Wednesday 15th April 2020)

Changed

  • The isMelodicDir() function now accepts directories that do not end with .ica, as long as all required files are present.

  • Added the dataclasses backport, so fslpy is now compatible with Python 3.6 again.

3.0.0 (Sunday 29th March 2020)

Added

Changed

  • fslpy now requires a minimum Python version of 3.7.

  • The default value for the partial_fill option to FileTree.read() has been changed to False. Accordingly, the FileTreeQuery calls the FileTree.partial_fill() method on the FileTree it is given.

  • The gifti.relatedFiles() function now supports files with BIDS-style naming conventions.

  • The run.run() and run.runfsl() functions now pass through any additional keyword arguments to subprocess.Popen or, if submit=True, to fslsub.submit().

  • The fslsub.submit() function now accepts an env option, allowing environment variables to be specified.

  • The run.runfsl() function now raises an error on attempts to run a command which is not present in $FSLDIR/bin/ (e.g. ls).

  • The bids module has been updated to support files with any extension, not just those in the core BIDS specification (.nii, .nii.gz, .json, .tsv).

  • The return value of a function decorated with fileOrImage(), fileOrArray(), or fileOrText() is now accessed via an attribute called stdout, instead of output.

  • Output files of functions decorated with fileOrImage(), fileOrArray(), or fileOrText(), which have been loaded via the LOAD symbol, can now be accessed as attributes of the returned results object, in addition to being accessed as dict items.

  • Wrapper functions decorated with the fileOrImage(), fileOrArray(), or fileOrText() decorators will now pass all arguments and return values through unchanged if an argument called submit is passed in, and is set to True (or any non-False value). Furthermore, in such a scenario a ValueError will be raised if any in-memory objects or LOAD symbols are passed.

  • The fileOrText() decorator has been updated to work with input values - file paths must be passed in as pathlib.Path objects, so they can be differentiated from input values.

  • Loaded Image objects returned by fsl.wrappers functions are now named according to the wrapper function argument name.

Fixed

  • Updated the prepareArgs() function to use shlex.split when preparing shell command arguments, instead of performing a naive whitespace split.

  • Fixed some bugs in the fslsub.info() and fslinfo.wait() functions.

  • Fixed the DeformationField.transform() method so it works with a single set of coordinates.

  • Image creation does not fail if loadMeta is set, and a sidecar file containing invalid JSON is present.

Removed

  • Removed the deprecated .StatisticAtlas.proportions, .StatisticAtlas.coordProportions, and .StatisticAtlas.maskProportions methods.

  • Removed the deprecated indexed option to Image.__init__().

  • Removed the deprecated .Image.resample method.

  • Removed the deprecated .image.loadIndexedImageFile function.

  • Removed the deprecatd .FileTreeQuery.short_names and .Match.short_name properties.

  • Removed the deprecated resample.calculateMatrix function.

2.8.4 (Monday 2nd March 2020)

Added

  • Added a new partial_fill option to FileTree.read(), which effectively eliminates any variables which only have one value. This was added to accommodate some behavioural changes that were introduced in 2.8.2.

2.8.3 (Friday 28th February 2020)

Fixed

2.8.2 (Thursday 27th February 2020)

Fixed

2.8.0 (Wednesday 29th January 2020)

Added

  • New Nifti.adjust() method, for creating a copy of a Nifti header with adjusted shape, pixdims, and affine. This can be useful for creating a resampling reference.

  • New affine.rescale() function, for adjusting a scaling matrix.

  • New mghimage.voxToSurfMat() function, for creating a voxel-to-freesurfer affine transform from any image.

Changed

  • Fixed a bug in the Mesh class to prevent indices from being loaded as floating point type.

  • Fixed a bug in the resample() function.

  • Fixed a bug in the MGHImage class, which was causing pixdims to be overridden by scales derived from the affine.

  • New makeWriteable() function which ensures that a numpy.array is writeable, and creates a copy if necessary

Changed

  • The GiftiMesh class no longer creates copies of the mesh vertex/index arrays. This means that, these arrays will be flagged as read-only.

  • The Mesh class handles vertex data sets requiring different triangle unwinding orders, at the cost of potentially having to store two copies of the mesh indices.

Changed

  • The Image.resample() method now supports images with more than three dimensions.

  • The fsl.utils.fslsub.submit() now returns the job-id as a string rather than a one-element tuple. It now also accepts a nested sequence of job ids rather than just a flat sequence. This will also changes the output from the function wrappers in fsl.wrappers if submitted.

  • Removed lxml as a dependency - this was necessary in older versions of trimesh.

1.6.0 (Friday January 26th 2018)

  • The new Mesh class is now the base class for all mesh types. It has been written to allow multiple sets of vertices to be associated with a mesh object (to support e.g. white matter, inflated, spherical models for a GIFTI/freeusrfer mesh).

  • The new VTKMesh class must now be used for loading VTK model files, instead of the old TriangleMesh class.

  • The new Mesh class uses the trimesh library (https://github.com/mikedh/trimesh) to perform various geometrical operations, accessible via new Mesh.rayIntersection(), Mesh.planeIntersection(), Mesh.nearestVertex() methods.

  • The Nifti and Mesh classes have new methods allowing arbitrary metadata to be stored with the image, as key-value pairs. These are provided by a new mixin class, Meta.

  • Freesurer surface files and vertex data can now be loaded via the FreesurferMesh class, in the new freesurfer module.

  • Freesurfer mgz / mgh image files can now be loaded via the new mghimage module. Internally, these image files are converted to NIFTI - the MGHImage class derives from the Image class.

  • The TriangleMesh class has been deprecated in favour of the new Mesh class.

  • Optional dependencies wxpython, indexed_gzip, trimesh, and rtree are now listed separately, so fslpy can be used without them (although relevant functionality will be disabled if they are not present).

1.5.4 (Wednesday January 10th 2018)

1.4.2 (Tuesday December 5th 2017)

1.4.1 (Thursday November 9th 2017)

  • Fixed bug in setup.py.

1.4.0 (Thursday November 9th 2017)

  • The uniquePrefix() function now raises a PathError instead of a ValueError, when an invalid path is provided.

  • The fsl.utils.async module is now deprecated, as async will become a reserved word in Python 3.7. It has been renamed to fsl.utils.idle, with no other API changes.

  • For image file pairs, the hdr extension now takes precedence over the img extension, when using the fsl.data.image.addExt() (and related) functions.

  • The fsl.utils.path.addExt() function accepts a new parameter, unambiguous which causes it to allow an ambiguous prefix, and return all matching paths.

  • New atlasq application, intended to replace the FSL atlasquery tool.

  • New imglob application, intended to replace the FSL imglob tool.

  • The Image.resample() method explicitly raises a ValueError if incompatible shapes are provided.

1.3.0 (Wednesday October 25th 2017)

  • Atlas classes can now pass kwargs through to the Image constructor.

  • LabelAtlas image values no longer need to match the index of the label into the AtlasDescription labels list. This means that label atlas XML files may contain non-sequential label values.

  • Cache now implements __getitem__ and __setitem__

  • The image.read_segments() function (monkey-patched into nibabel) is deprecated, as it is no longer necessary as of nibabel 2.2.0.

  • platform.isWidgetAlive() is deprecated in favour of an equivalent function in the fsleyes-widgets library.

  • scipy is now explicitly listed as a requirement (this should have been done in 1.2.1).

1.2.2 (Saturday October 21st 2017)

  • The image.read_segments() function is only monkey-patched into nibabel 2.1.0, as it breaks when used with 2.2.0.

1.2.1 (Saturday October 7th 2017)

  • If an Image is passed an existing nibabel header object, it creates a copy, rather than using the original.

  • New Image.resample() method, which resamples the image data to a different resolution.

  • New LabelAtlas.coordLabel(), LabelAtlas.maskLabel(), ProbabilisticAtlas.coordProportions() and ProbabilisticAtlas.maskProportions() methods. The coord methods perform coordinate queries in voxel or world coordinates, and the mask methods perform mask-based queries.

1.2.0 (Thursday September 21st 2017)

  • fsl.data.image.Nifti.voxelsToScaledVoxels() method deprecated in favour of new Nifti.voxToScaledVoxMat() and Nifti.scaledVoxToVoxMat() properties.

1.1.0 (Monday September 11th 2017)

1.0.5 (Thursday August 10th 2017)

  • transform.veclength() calculates the length of a vector

  • transform.normalise() normalises a vector

  • transform.scaleOffsetXform() adjusted to have more flexibility with respect to inputs.

  • transform.decompose() can return rotations either as three axis-angles, or as a rotation matrix
