I am currently trying to run CASTEP calculations on MiB structures, however I receive nothing but errors. The first error I receive frequently is the CASTEP calculation failing to run due to the error message "Failed to import document from..." and it is extracting the structure from the right folder. If this error does not occur the CASTEP calculation on the structure will run successfully however I will be unable to produce a Band Gap value because this error message "View band structure in CASTEP Analysis: To plot band structure more than one k-point is needed." I have yet to run a successful CASTEP calculation and produce the band structure on 10 different MiB structures. Any ideas on how to fix this? Thank you.
