SCHAKAL is a FORTRAN program for the graphical representation of molecular and solid-state structure models. Its .schakal files contain chemical modeller input data used to define these models.
The format is specific to SCHAKAL rather than being a general-purpose chemical structure exchange format, so the files are most useful with the SCHAKAL program.
Open a .schakal file with the SCHAKAL program by E. Keller on a system that supports this legacy FORTRAN software. The program interprets the chemical modeller input data and displays the molecular or solid-state structure.
A text editor may allow the contents to be viewed or edited, but it will not display the structure or validate the input as SCHAKAL does.
Open the .schakal file in SCHAKAL and use any export options provided by the installation to create output in another format.
Without SCHAKAL, using the data in another chemical modelling program may require manually recreating the molecular or solid-state model.
