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. .TP \fB\-m\fR MASK, \fB\-\-mask\fR MASK single mask item .TP \fB\-o\fR OUTPUT, \fB\-\-output\fR OUTPUT output filename ('.hdf5' extension is added automatically if necessary). .TP \fB\-c\fR CHANCE_LEVEL, \fB\-\-chance\-level\fR CHANCE_LEVEL chance level performance .TP \fB\-s\fR {t,z,p}, \fB\-\-stat\fR {t,z,p} Store corresponding statistic, e.g. z\-value corresponding to the original t\-value .TP \fB\-a\fR {greater,less,two\-sided}, \fB\-\-alternative\fR {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 \fB\-\-\fR the 'less' .TP \fB\-\-isample\fR ISAMPLE In case of multi sample dataset, which sample to extract to run the ttest on .SH AUTHOR Written by Michael Hanke & Yaroslav Halchenko, and numerous other contributors. .SH COPYRIGHT Copyright \(co 2006\-2016 PyMVPA developers .PP Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: .PP The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. .PP THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
