Shape Tools Array IO library project definition

Overview

a small library that enables reading and writing numerical arrays to and from disk files.

Written in Java 1.5
support comments
support float, and double precision
support intermixed scientific notation and decimal notation.
disk files are self identifying
- array dimensions, data type
support an application versioon number
support a general array io version number
support
- Nifti files
- support landmark warp files (?)
- support Ryan's discrete data files
support calls like
- float [][] foo = readArray("myArray.file");
- readArray(foo, "myArray.file");
Provides means to:
- Ensure that the data values are not used inappropriately.
- Communicate to library clients contextual descriptions of the data (e.g. 'this is a set of samples').
have means to require existence of a named data chunk in the input file (to assure application the the file matches the intended use).
should have non-lossy translations between common formats
be able to specify validity constraints on arrays before reading (e.g "must be square", "must be 4 or more columns", "must be a "myType" data file,
be able to specify comments to be written out (where approprite)
be able to change to numerical formatting of the values , if written to text.
