The data should be binary, indeed with matlab I'm not reading it as a text and it works fine. Another hint, a friend of mine wrote a c++ code that outputs the correct numbers and it works:
// Read the pink photon data arg_file.read(num_photons_bin, 1); pink_photons = (unsigned int) *num_photons_bin; // Increment the counter based on the bytes read status_counter += 1; // Read pink photon data for (int photon = 0; photon < pink_photons; photon++) { // Read the binary data into the variable arg_file.read((char *)&pink_x_pos, sizeof(double)); arg_file.read((char *)&pink_y_pos, sizeof(double)); arg_file.read((char *)&pink_z_pos, sizeof(double)); arg_file.read((char *)&pink_num_scatters, sizeof(int)) +; arg_file.read((char *)&pink_col_scatters, sizeof(int)) +; arg_file.read((char *)&pink_energy_val, sizeof(double) +); }

So to my understanding this is a bin file. Regarding the hexdump, unfortunately the file has a 32768bytes header so I don't know how to skip them for the hexdump (what do I have to put instead of "head"?).
Thank you very much for your attention.
