I am reading a binary phase space file (* .egsphsp #), for simulations monteCarlo with EGSnrc.
My problem is in the file header. The floating variables read them in 1 byte with fread, however, the characters are read in 2 bytes, which causes problems when I generate my own phase space file, since fwrite writes the characters in 1 byte and as double.
Part of my codes:
READ
fprintf ('Reading phase space file ... \ n')
MODE_RW = setstr (fread (fid, 5, 'uchar')) '; % Mode
NPPHSP = fread (fid, 1, 'int32');
NPHOTPHSP = fread (fid, 1, 'int32');
EKMAXPHSP = fread (fid, 1, 'float32');
EKMINPHSP = fread (fid, 1, 'float32');
NINCPPHSP = fread (fid, 1, 'float32');
Header_File = struct ('Mode', MODE_RW, 'total_particles', ...
WRITE
MODE_RW = Header_File.Mode;
NPPHSP = Header_File.total_particles;
NPHOTPHSP = Header_File.total_photons;
EKMAXPHSP = Header_File.Max_energy;
EKMINPHSP = Header_File.Min_energy;
NINCPPHSP = Header_File.particles_source;
fid_w = fopen ('prueba.egsphsp1', 'wb');
g = 1;
if g == 0
a = fwrite (fid_w ,MODE_RW, 'uchar');
b = fwrite (fid_w, NPPHSP, 'int32');
c = fwrite (fid_w, NPHOTPHSP, 'int32');
d = fwrite (fid_w, EKMAXPHSP, 'float32');
e = fwrite (fid_w, EKMINPHSP, 'float32');
f = fwrite (fid_w, NINCPPHSP, 'float32');
.

'a' and 'MODE_RW' are not of the same class and have different bytes.
I need to read five characters in 5 bytes (1 byte / char). How do I do it?
