[ccp4bb] shape complementarity using NMR structures

[Sollepura Yogesha]

Hello Everyone,

I am trying to calculate shape complementarity of NMR structure (1U89) using 
CCP4 Sc.

I get following error

 $WARNING: NO CRYST CARDS READ$

<B><FONT COLOR="#FF0000"><!--SUMMARY_BEGIN-->
 
 $TEXT:Warning: $$ comment $$

Any advice is highly appreciated.

Thanks in advance.

Yogesha
