Description Usage Arguments Details Value Author(s) References See Also Examples

These functions read in the header information and multi-dimensional array from a binary file in Analyze 7.5 format.

1	readANALYZE(fname, SPM = FALSE, verbose = FALSE, warn = -1)

fname

Pathname of the Analyze pair of files .img and .hdr without the suffix.

`SPM`	is a logical variable (default = `FALSE`) that forces the voxel data values to be rescaled using the funused1 ANALYZE header field. This is an undocumented convention of ANALYZE files processed using the Statistical Parametric Mapping (SPM) software.
`verbose`	is a logical variable (default = `FALSE`) that allows text-based feedback during execution of the function.
`warn`	is a number to regulate the display of warnings (default = -1). See `options` for more details.

The internal functions readBin and rawToChar are utilized in order to efficiently extract information from a binary file. The types of data are limited to 1- and 2-byte integers, 4-byte floats and 8-byte doubles.

An object of class anlz is produced.
