Changes:
CONN 17.c change.log
Cumulative patch, bug fixes and improvements
Added ability to run preprocessing steps for individual
sessions/runs (this facilitates incrementally adding new timepoints
to an existing CONN project in longitudinal analyses)
Added QA plots: QA_artifact movie display of BOLD volumes with ART
global/motion/outlier timeseries, QA_registration plots display
original or eroded white/csf masks
Added option to annotate individual QA plots
Added QA subject-level measures QA_MotionMax/Mean and
QA_GlobalMax/Mean from ART-derived framewise motion and BOLD change
timeseries
(*) Changed default MNI preprocessing pipeline (minor changes):
a) moved ART step to be performed before functional normalization
instead of after it (this allows the functional normalization step
to use a mean-functional image generated by ART which excludes
outlier scans, making coregistration/normalizatoin procedures more
robust to the presence of outliers)
b) changed 'functional_normalize' to
'functional_segment&normalize' (this generates additional
functional gray/white/csf masks to be used in QA plots or as
alternative aCompCor masks)
For back-compatibility or mid-analysis updates: the exact prior
pipeline can be loaded from:
conn/utils/preprocessingpipelines/defaultMNI_legacy.mat
Added compatibility-fix for cluster-computing options in new
SPM+toolboxes standalone ("batteries included" standalone SPM12
prerelease)
Added GUI options to easily select different functional,
structural, ROI, or first-level covariate files using filename
rules (see 'reassign all files' options in
functional/structural/roi/covariate tools menus)
Added movie displays of functional timeseries (see 'display
single-slice for all timepoints' options in functional/first-level
covariate tools menus, and 'display values' option in Denoising
tab)
Added "art_regression_timeseries*.mat" file output to ART and
associated QA_timeseries 1st-level covariate in CONN, containing
(when using default ART settings) scan-to-scan changes in global
BOLD signal (z-scores), and framewise displacement timeseries (mm)
(timeseries that, when thresholded, lead to identified outlier
scans)
Added "carpet" display of BOLD signal timeseries to Denoising tab
and QA plots (similar to Power et al 2017) to help evaluate the
amount of residual whole-brain signals before and after denoising
Added ability to edit through the GUI and batch commands the
binarization/erosion options for grey matter, white matter, and CSF
masks (see Setup.ROIs.Erosion settings; previous
batch.Setup.cwthreshold field)
Added voxel BOLD signal timeseries display to GUI (click on brain
images on Setup.functionals, Denoising, or First-level analysis
tabs)
Added voxel-level "plot effects", "plot values", and "import
values" menus to Second-level results tab (click on brain images on
Second-level results tab)
