mrcImageLowPassFilter is Eos's Command that performs Low-Pass Filter to mrcImage, and smoothing it.

List of option

Main option

Option Essential/Optional Description Default
-i Essential Input: mrcImage NULL
-o Essential Output: mrcImage NULL
-hvp Optional HalfValuePoint[A-1] (the spatial frequency that the intensity attenuate to half) 1.0
-w Optional Width of cos function of spatial frequency 1.0
-c Optional ConfigurationFile NULL
-m Optional Mode (need to set ,because 0 is undefined) 0
-h Optional Help 　

-m details

Value Description
1 Step filter : required argumnent: -hvp
2 Cos filter  : required argumnent: -hvp -w
3 Exp filter  : required argumnent: -hvp
4 Gauss filter  : required argumnent: -hvp
5 Lorenz filter  : required argumnent: -hvp
