Hi Smita,

The '.sin' file is simply a set of 2D projection images. It can be analysed by MATLAB, using the following commands: 

fid = fopen ('[your output name]', 'r');
projection = fread (fid, 'uint16');
fclose (fid);
projection = reshape (projection, dim1, dim2, dim3); % dim1, dim2 and dim3 are dimensions of the .sin file
Alternatives are completely free tools: ImageJ and Amide. In both tools, once the image is selected, you must select the image type as 16-bit unsigned, little Endian.

Please have a look at the following links which direct you to the ImageJ and Amide web-sites, respectively:

ImageJ: http://rsbweb.nih.gov/ij/

Amide: http://amide.sourceforge.net/index.html

The '.hdr' file is also a header-file which contains GATE interfile-output information. Such a file will help you to identify .sin file specifications such as height, width and number of projection images (dim1, dim2 and dim3, respectively). 

Good work,
