NAME
scatter - simple t-test routine
SYNOPSIS
pymvpa2 ttest [--version] [-h] -i DATASET [DATASET ...] [-m MASK] -o OUTPUT [-c CHANCE_LEVEL] [-s
{t,z,p}] [-a {greater,less,two-sided}] [--isample ISAMPLE] t-test across multiple volumes against some
chance level
DESCRIPTION
scatter not available: No module named _tkinter, please install the python-tk package
This is a rudimentary way to perform fixed-effect significance test across subjects on e.g. searchlight
results maps.
OPTIONS
--version
show program's version and license information and exit
-h, --help, --help-np
show this help message and exit. --help-np forcefully disables the use of a pager for displaying
the help.
-i DATASET [DATASET ...], --input DATASET [DATASET ...]
path(s) to one or more PyMVPA dataset files. All datasets will be merged into a single dataset
(vstack'ed) in order of specification. In some cases this option may need to be specified more
than once if multiple, but separate, input datasets are required.
-m MASK, --mask MASK
single mask item
-o OUTPUT, --output OUTPUT
output filename ('.hdf5' extension is added automatically if necessary).
-c CHANCE_LEVEL, --chance-level CHANCE_LEVEL
chance level performance
-s {t,z,p}, --stat {t,z,p}
Store corresponding statistic, e.g. z-value corresponding to the original t-value
-a {greater,less,two-sided}, --alternative {greater,less,two-sided}
Which tail of the distribution 'interesting' values belong to. E.g. if values are accuracies, it
would be the 'greater', if errors -- the 'less'
--isample ISAMPLE
In case of multi sample dataset, which sample to extract to run the ttest on
