Dear list, I am trying to use a pcomb syntax from an earlier post for vignetting correction (using the polynomial y = -9E-09x5 + 1E-06x4 - 4E-05x3 - 0.0003x2- 0.0637x + 21.223 ): pcomb -e 'sq(x):x*x;r=sqrt(sq(2/xres*x-1)+sq(2/yres*y-1))' \ -e 'sf=-9E-09*r^5 + 1E-06*r^4 - 4E-05*r^3 - 0.0003*r^2 - 0.0637*r + 21.223' \ -e 'ro=sf*ri(1);go=sf*gi(1);bo=sf*bi(1)' fisheye_28.hdr > corrected.hdr I am getting "no such file or directory" error. Still, pcomb writes a 65kb output file with the name I defined. First I thought it could be a problem related to the path or installation so I tried to run including the full path of both input and output images but got the same result. I also tried the command on a Mac and got the same error. I checked the path on the Mac and it seems correct. Environmental variables and registry entries look ok on the windows machine, too. Every other command seem to work fine. Am I missing something in the syntax? Thank you,
Alp
