Dear Muhammed,

that's not uncommon. Your protein might undergo domain movements or
contain flexible parts.

if your structure contains any loops / floppy regions (with high
B-values), you can exclude them from the search model.

If it is composed of domains, chop it into pieces and search with one
after the other, starting from the largest one.
