6.4.1. USE OF EXTERNAL FILES, BATCH RUN MODE

next, previous Section / Table of Contents / Index When BALSAC is started from the DOS or Unix command line two external files must be present in the calling subdirectory or linked appropriately. The first file is used for basic parameter initialization and its name is defaulted to 'balsac2.ini'. The second file provides on-line help text, see Sec. 6.4.11, and its name is defaulted to 'balsac2.hlp'. Other names for both files can be explicitly given on the command line, see Sec. 6.1, or with the basic parameter option, see Sec. 6.2.15. BALSAC can be run with input from external structure files, see Secs. 6.1, 6.2.11, 6.3.9. Here all structure information is loaded from the file after which BALSAC proceeds to the main option menu for interactive input. In addition, both BALSAC/LATTICE and BALSAC/CLUSTER sessions offer a batch run mode where instead of interactive input a fixed sequence of options (only options of the main option menu are available at present) is executed. This sequence is determined by option flags provided with the external input file, see Secs. 6.4.2, 6.4.3. Names of structure input files are given on the command line, see Sec. 6.1, or with the file input options, see Secs. 6.2.11, 6.3.9. Structure files are generated interactively in BALSAC sessions (different formats are available, see Secs. 6.4.2-6) or can be created with a text editor. However, only LATUSE format (LATTICE session) or PLOT3D format files (CLUSTER session) are accepted for input to BALSAC. For file name conventions see also Sec. 5.6. BALSAC file output includes PostScript format which allows you to generate high resolution gray scale or color PostScript prints of structure graphics on PostScript laser printers or typesetting devices to be used for publication. The PostScript format together with advise on simple modifications is described in detail in Secs. 6.4.6, 6.4.6.1. Further, BALSAC file output includes a raw binary format which is used to save CLUSTER or LATTICE screen graphics as pixel images, see Secs. 6.2.8, 6.3.6. Raw binary format files can be used outside BALSAC to produce image sequences for animation or fast display of fixed views, see Secs. 6.4.7, 6.5.2. next, previous Section / Table of Contents / Index
