Detailed Description
DCD Trajectory file format. This class enables BALL to write DCD files that can be read by VMD. The format stems from the xplor package. This format is NOT portable.
- The header is described in the documentation for the nested DCDHeader class.
- Header of a DCD file: Got this description from http://www.arl.hpc.mil/PET/cta/ccm/software/fmd/Docs/html/fmd_ug.html. Quote: "The exact format of these files is quite ugly, as it reproduces the binary record format of unformatted FORTRAN files. Each such "record" begins with 4 bytes containing the integer value of the number of bytes in the following record. It ends with a record containing the same 4 bytes."
- The header consists of several blocks. Each block starts and ends with the number of bytes enclosed between those numbers, i. e. a block consisting of 8 bytes starts with the number 8 followed by 8 bytes of data and ends with the number 8.
