The order of bytes in a data word is described by its endianess. With high (big) endian byte order the bytes are numbered consecutively from left to right in a word. With little endian byte order the byte numbering is reversed as you go from right to left. The format of a spectrum is given in the following manner:
levels.lines.columns.element format:[version]
like for example
1k.2k.4k.he4
which characterizes a cube with 1024 levels, 2048 lines and 4096 columns with 4-byte elements (total size = 35 GB) coded in high endian format.
Allowed abbreviations in the sizes of levels, lines and columns are:
