GPR-SLICE Update - October 17, 2019 - 142pm Pacific  

GPR-SLICE Library Update - September 25, 2019 - 1115pm Pacific

note:   With multithreading one can speed up radargram signal processing, data conversion, gridding, time 0 editing, and slice binning data processing  by engaging this option and setting the number of logical cores desired to use in the Options menu.  For an average system with 4 or 8 logical cpu cores one can expect nearly 4-8  times speed in processing!     

note: Multithread processing requires the library update as well

GPR-SLICE educational license update - August 28, 2019

note:  This will be the last update for the educational license as this option is being discontinued.
