Changes in Nipype

Release 0.3.4 (Jan 12, 2010)

• API: hash values for float use a string conversion up to the 10th decimal place.

• API: Iterables in output path will always be generated as _var1_val1_var2_val2 pairs

• ENH: Added support to nipy: GLM fit, contrast estimation and calculating mask from EPI

• ENH: Added support for manipulating surface files in Freesurfer:

  • projecting volume images onto the surface
  • smoothing along the surface
  • transforming a surface image from one subject to another
  • using tksurfer to save pictures of the surface

• ENH: Added support for flash processing using FreeSurfer

• ENH: Added support for flirt matrix in BBRegister

• ENH: Added support for FSL convert_xfm

• ENH: hashes can be updated again without rerunning all nodes.

• ENH: Added multiple regression design for FSL

• ENH: Added SPM based Analyze to Nifti converter

• ENH: Added increased support for PyXNAT

• ENH: Added support for MCR-based binary version of SPM

• ENH: Added SPM node for calculating various threshold statistics

• ENH: Added distance and dissimilarity measurements

• BF: Diffusion toolkit gets installed

• BF: Changed FNIRT interface to accept flexible lists (rather than 4-tuples)

  on all options specific to different subsampling levels

Release 0.3.3 (Sep 16, 2010)

• API: subject_id in ModelSpec is now deprecated
• API: spm.Threshold - does not need mask, beta, RPV anymore - takes only one image (stat_image - mind the name change) - works with SPM2 SPM.mat - returns additional map - pre topological FDR
• ENH: Added support for Diffusion toolkit
• ENH: Added support for FSL slicer and overlay
• ENH: Added support for dcm2nii
• BF: DataSink properly handles lists of lists now
• BF: DataGrabber has option for raising Exception on getting empty lists
• BF: Traits logic for ‘requires’ metadata
• BF: allows workflows to be relocatable
• BF: nested workflows with connections don’t raise connection not found error
• BF: multiple workflows with identical nodenames and iterables do not create nestsed workflows

Release 0.3.2 (Aug 03, 2010)

Enhancements

• all outputs from nodes are now pickled as part of workflow processing
• added git developer docs

Bugs fixed

• FreeSurfer
  • Fixed bugs in SegStats doctest

Release 0.3.1 (Jul 29, 2010)

Bugs fixed

• FreeSurfer

  • Added group t-test to freesurfer tutorial

Release 0.3 (Jul 27, 2010)

Incompatible changes

• Complete redesign of the Interface class - heavy use of Traits.
• Changes in the engine API - added Workflow and MapNode. Compulsory name argument.

Features added

• General:
  • Type checking of inputs and outputs using Traits from ETS.

  • Preliminary Slicer and AFNI support.
  • New flexible DataGrabber node.
  • AtlasPick and Threshold nodes.
  • Preliminary support for XNAT.
  • Doubled number of the tutorials.
• FSL:
  • Added DTI processing nodes (note that TBSS nodes are still experimental).
  • Recreated FEAT workflow.
• SPM:
  • Added New Segment and many other nodes.
  • Redesigned second level analysis.
