ba2s - BSU program converts ascii text file to bsegy format (C-Language Version)
ba2s [ -h | infile | iorder | ncol | nrow | dt ]
Basic Seismic Utilities (BSU) converts an ASCII text file to BSEGY format. No geometry setting, just sample interval transfered to headers. Text file must consist of a matrix of values. The columns can be either channel or time axis. Rows can be either channel or time axis. One uses parameter iorder to select definition of columns and rows. The specification of number of rows and columns can not exceed number in file, but may be less than the actual values. Numbers must be separated by one or more space characters. BSEGY header limits trace length to a maximum (16bit=32767). C-Language Version.
