This par file must also exist for unblocked data files. The par file must be created by hand for unblocked data files. The par files are in text and so can be edited, but beware, it is important that only the referencing and file name be edited. The processing programs all have an associated 'script' file, which specifies the input par file, the output data file, and whatever other parameters are needed. Blanks lines are allowed.
White space separates parameters in a line.
Dimensions of data always present a problem with conventions. In Azara the dimension of data that is 'fastest' on disk is 'dim 1', the dimension that is second fastest is 'dim 2', etc. Thus the acquisition dimension in NMR experiments will be dimension 1. Point counting is another place where there is a problem with conventions. In par files, points are counted in real points, even for complex data.
