Re: Reference to non-existent field 'channels'. Error in pfs_read_luminance (line 25) Y = pin.channels.Y;

Hi,

Please run

pfs_test_shell

from matlab and post its output. Most probably pfsin is not found in
the shell path. Check if you can execute:

system( 'pfsin h1.hdr | pfsview' );

Hi
I ran pfs_test_shell and it was ok but when I ran system( 'pfsin h1.hdr | pfsview' );
it showed this error

system( 'pfsin h1.hdr | pfsview' );

/bin/bash: pfsin: command not found
/bin/bash: pfsview: command not found
what shold I do whenever I ran
>> pfs_read_image('memorial.hdr');
I get this error.

Reference to non-existent field 'channels'.

Error in pfs_read_image (line 33)
  if( isfield( pin.channels, 'X' ) && isfield( pin.channels, 'Z' ) )

Regards

Before starting matlab (from terminal) you need to make sure that pfs* commands are in the system path. On Linux (assuming you use bash):

export PATH=<path-to-bin-folder-with-pfs-commands>:$PATH

Hi Rafal
when I have started matlab from terminal and then in matlab i ran
img=pfs_read_image('memorial.hdr');

Reference to non-existent field 'channels'.

Error in pfs_read_image (line 33)
  if( isfield( pin.channels, 'X' ) && isfield( pin.channels, 'Z' ) )

 I test this function with .exr and .tif images and matlab's out put was the same , and in terminal I got these errors
/usr/local/bin/pfsin: line 107: pfsinexr: command not found
tif files unsupported. Compile pfstools with ImageMagick or libtiff.

pfsinrgbe error: Can not open file 'memorial.hdr'

furthermore when I saw the content of /usr/local/bin I could not find these functions:
pfsinexr
pfsinppm
pfsout exr
pfsoutrgb
pfsv
pfsview
pfsoctavergb
pfsoctavelum
I don't know what is the problem, perhaps compiling has error because when I run cmake ../
it can not find openmp flag, but after I ran make it can build the files. I don't know what is my problem please help me.

Regards
