File Format



On an ADAKOS disk, a file consists of two parts: the so-called --1 sector and the actual file data. The --1 sector is is a sequence of 256 24 bit words (or 768 bytes). Its first part contains ADAKOS file information such as file name, file size etc. as described in the ASPECT system software manual. Its second part contains DISNMRacquisition and processing parameters, if the file is a DISNMR data file. The program TCP always sends the --1 sector, followed by the actual file data to the network or archive in form of a byte stream. After the file having arrived on the destination device, it will consists of a sequence of bytes. The first 768 bytes represent the --1 sector, all following bytes form the file data. Three adjacent bytes form a 24 bit ASPECT word with the following byte ordering: the first byte of a 3-byte block represents bits 7-0 of an ASPECT word, the second byte bits 15-8, and the third one bits 23-16.

This file format is valid for all types of ASPECT files sent off, such as DISNMR data files, text files, program files etc. DISNMR data files can be converted to UXNMR or WINNMR data sets by the conversion commands of these programs. ASPECT text files can be converted to UNIX or DOS format via the aspcon program described earlier.
