I am using FCART for analyzing Gaussian 09 spectra of some molecules. I have some problems with the size of some systems. I would like to know people using this software.
FCART is great for analyzing vibrational spectra from Gaussian, but large systems can be challenging due to memory and processing requirements. Optimizing Gaussian output and simplifying large molecules can help improve performance. Overall, FCART provides valuable insights, but may need some adjustments for larger systems.

Hi. Thanks for the answer. The attached paper is quite interesting, but I am looking for help regarding real calculation times form people using Fcart.
