ecatcalc 1.6.1 © 2002-2013 by Turku PET Centre
Simple arithmetic calculations on ECAT 6.3 and ECAT 7 files.
Usage:
ecatcalc [Options] <Image1> <Operation> <Image2|Const> <Output img>
, where
Operation = +, -, x , /
Const = Image1 is operated with this value
Options:
-f or -frames
All frames in image1 are processed with 1st frame of image2
-m=<value> or -max=<value>
Upper limit for output pixels
-h or --help
Print this message and exit
--version, or --build
Print software build information and exit
--silent
Program works silently, printing only warnings and error messages
--verbose
Program prints more information about what it is doing.
Examples:
ecatcalc a999.flow.img - a1000.flow.img subtr.img
ecatcalc o657dy1.v / 2.34 o657rda.v
ecatcalc -f -m0.25 l333dy1.scn x l333.nrm l333dy1.corr.scn
Image1 and image2 must be in the same format, and they must have same
matrix size and plane numbers.
Data is not interpolated or corrected for physical decay, and thus it is
on the responsibility of the user to check that PET frame times are similar
and that physical decay and other corrections are appropriately considered.
