Hi Matthew,
Thank you for all your help. I have made some progress. I am running fslnets completely under OCTAVE 4.0.2 on a ubuntu 12.04 LTS. fslnets runs almost to completion except when trying to read my set of png files.
Here is the error message:
GD Error: gd-png: fatal libpng error: bad parameters to zlib
GD Warning: gd-png error: setjmp returns error condition 2
/data/OBSCURE/DR/melodic_IC.sum/0016.png is not a valid png2 or gif file
I have tried it with imagemagick and with the graphmagick-compat packages.
And the same error comes up.
I ran the imagemagick identify command on my set of png files and they are all png file formats.
Please kindly advise.
Thanks, Jasmin
