Figure . Example submission process with digichem submit. In each case, only the starting geometry is taken from the given input file, while any calculation options (in the case of the Gaussian .com file) are ignored. Submission in Digichem is achieved using the digichem submit sub-module. Any number of coordinate and/or method files can be specified at once. Each coordinate file will spawn a calculation to be run in parallel with the other coordinate files, while each method will be queued up to be performed in series using the output geometry from the previous calculation step (Figure ).
