Ricardo Tadeu Maia

Hello, @Osama Ibrahim.

This error occurs when some of your parameters get anomalous values (like Unit cell axis a,b or c =0, which is impossible). So, review your parameters, like unit cell dimensions and angles, background, scale factors, etc.

Best regards,

Ricardo Tadeu

Hi @Ricardo Many thanks for your comment. I'll check those parameters.
