gauss_4dfp
spatial frequency domain
Usage: gauss_4dfp <4dfp|conc input> f_half [outroot]
Examples:
gauss_4dfp pt349_study9to9 0.1
gauss_4dfp p1234ho5 0.7 p1234ho5_g7
Options
outroot |
output file name (default = <inroot>_g<10*f_half>) (only for 4dfp input) |
-@<b|l> |
output big or little endian (default input endian) |
-w |
(wrap) suppress x and y padding |
-d |
differentiate |
N.B.: f_half is half frequency in 1/cm N.B.: FWHM*f_half = (2ln2/pi) = 0.4412712 N.B.: conc files must have extension “conc”
imgblur_4dfp
spatial domain
Usage: imgblur_4dfp [options] <image_file> <FWHM_in_mm>
Examples:
imgblur_4dfp -yz vc345 5.5
Options
-x |
selective x blur |
-y |
selective y blur |
-z |
selective z blur |
-@<b|l> |
output big or little endian (default input endian) |
N.B.: default blur is 3D isotropic
hsphere_4dfp
convolve image with hard sphere kernel
Usage: hsphere_4dfp <file_4dfp> <flt>
Examples:
hsphere_4dfp np1234_zmap_222 5
N.B.: second argument specifies hard sphere radius in mm
