How to read a .dat file and creat a 3D image

Hello there,

There's a .dat file in which the value at each voxel is 1 (solid) or 0 (pore). Dose anyone know how to import this .dat file into Matlab and creat a 3D image of porous media?

Thank you,

Rick

first u need to know:

• how the data is stored (in 2D it is very straightforward, but not in 3D): is it slice by slice (which plane, xy,xz,or yz)
• data type and format (binary, or integer?)
• data size for each dimension x,y,z

fileid = fopen('mydata.dat','r');

data = fread(fileid, inf, 'single', 'ieee-be'); %read till the end of file

data = reshape(data,[dimx dimy dimz]); % reshape data
