Computer Requirements
SEDFIT and SEDPHAT
* Windows PC with at least 500 MHz, 256 MB RAM, Pentium or Xeon processor (Cyrix 3 processors may not work). Multi-core processors are supported and can significantly speed up many computations. Best performance is obtained with high processor speed, large RAM, fast hard drive access is recommended, as well as a generous amount of graphics card memory. * ~10 MB of disk space * internet connection for accessing on-line help Please sign up for the SEDFIT Users Group to post questions reaching ~ 250 other users, read exchanges of experience and tips for the SEDFIT software and AUC in general. If you are using SEDPHAT, Please sign up to the SEDPHAT-L listserv for discussion of applications of SEDPHAT and questions of global analysis of ITC, AUC, and other biophysical techniques. For both SEDFIT and SEDPHAT, you can sign up for update information at SEDFIT-UPDATE and SEDPHAT-UPDATE, respectively.
EVILFIT
Evilfit requires installation of 32-bit Matlab Compiler Runtime library from Mathworks (MRC v 7.17, Release R2012a). Note: the MRC will conflict with previous installations of MATLAB.
