The syntax of ORCHESTRA input files 01/01/2024 An input file contains a set of data points that are read into one or more cells/nodes as defined in the concert file. A line starting with "Var:", followed by a list of names on the same line defines the variables that are used for input. After that one or more lines starting with "Data:" define the values of the variables. Names and values are separated by tabs or spaces. Example: Var: pH pe Data: 7.2 3.8 Data: 6.0 12.3 Data: .... ..... Because in this format each data and variable line is individually indicated, it is possible to have different data blocks with different variables in a single input file. It is also possible to use loops (sweeps) in this type of input file. However, to be more compatible with other codes and languages it is also possible to use an alternative format without the "Var:" and "Data:" keywords. Example: # Alternative format e.g. compatible with Python. # This is a comment # pH pe 7.2 3.8 6.0 12.3 .... .....
