示例1: transformData
# 需要导入模块: from ClearMap import IO [as 别名]
# 或者: from ClearMap.IO import transformData [as 别名]
def transformData(source, sink = [], transformParameterFile = None, transformDirectory = None, resultDirectory = None):
"""Transform a raw data set to reference using the elastix alignment results
If the map determined by elastix is
:math:`T \\mathrm{fixed} \\rightarrow \\mathrm{moving}`,
transformix on data works as :math:`T^{-1}(\\mathrm{data})`.
Arguments:
source (str or array): image source to be transformed
sink (str, [] or None): image sink to save transformed image to. if [] return the default name of the data file generated by transformix.
transformParameterFile (str or None): parameter file for the primary transformation, if None, the file is determined from the transformDirectory.
transformDirectory (str or None): result directory of elastix alignment, if None the transformParameterFile has to be given.
resultDirectory (str or None): the directorty for the transformix results
Returns:
array or str: array or file name of the transformed data
