AI Summary: The user is experiencing issues with the PDFfit functionality within the RMC module of GSAS-II, specifically when attempting to analyze PDF data from the Ni tutorial. The problem appears to be related to the software's inability to properly read the data, resulting in a missing 'RMC' section and no output. The task involves troubleshooting this data reading issue, potentially involving investigation of GSAS-II's configuration, dependencies (like diffpy.pdffit), and the tutorial's data file itself.
