Version 1.8.4 Beta (Dec 13, 2022)#
Critical Alert for fMRIPrep-Options in C-PAC v1.8.1 - v1.8.3
Fixed a bug that was causing
single_step_resampling, when combined with certain other configurations, to inadvertently cause unexpected forks in the pipeline past transform application.
This bug caused any affected
fmriprep-options-basedpipeline configurations (including
rbc-options) to produce BOLD time series write-outs to the output directory in template space which were not nuisance regressed or filtered, for C-PAC versions 1.8.1 through 1.8.3.
Although these outputs were not expressly labeled as nuisance regressed or filtered, they were labeled as preprocessed with
desc-preprocand were the only functional data transformed to template space and used for downstream processing, such as ROI-based timeseries extraction.
If you are unsure if you have been affected, you can check the side-car JSON for your template-space BOLD data from these versions for those pipeline configurations, as the JSON will still accurately reflect what operations had been performed on the data.
Summary Here’s what’s new with C-PAC Version 1.8.4
RBC-options pipeline RBC-options pipeline was built and integrated in C-PAC based on the Reproducible Brain Charts initiative, which aims to aggregate and harmonize phenotypic and neuroimage data to delineate node mechanisms regarding developmental basis of psychopathology in youth and yield reproducible growth charts of brain development (Scopel Hoffman et. al., 2021)

Surface outputs Previously in C-PAC, the main output for the surface pipeline was the CIFTI timeseries (.dtseries) file. Now we are also outputting CIFTI parcellations (.dlabel) in Desikan-Killiany and Destrieux spaces in 164K and 32K resolutions.

Pipeline Harmonization Updates
rbc-optionsconfiguration, based on the Reproducible Brain Charts (RBC) initiative.
Updated XCP-QC files to better adhere to the PennLINC XCPEngine pipeline.
Surface pipeline now outputs 164k and 32k CIFTI parcellations in each of Desikan-Killiany and Destrieux spaces to output directory.
Added a log of expected outputs, generated at the beginning of each C-PAC run.
Made ndmg correlation matrices a configurable option, as it used to automatically run for all pipelines before.
Made surface output filenames more BIDS-compliant.
Added the ability to follow symlinks for BIDS directories.
Updated templates used for rodent pipeline and added outputs that were missing.
Added the ability to disable the exception raised if the initial resource check estimates more memory is needed.
--runtime_bufferflags and related pipeline config entries and functionality.
Added additional error checks and a more informative message for node block connecting in the engine.
Expanded some surface post-processing workflows to be more flexible with other pipeline configurations.
Added list of preconfigured pipelines to the usage string.
Relicensed C-PAC from BSD-3-Clause to LGPL-3.0-or-later.
