There is no common residues in the input structures

Dear TM-score Designer,

I downloaded the TMscore.f and compiled it on my machine. Then I try to compute the TM score of two protein fragments that are form the same chain of a protein, 1WDY. According to an article, they should have TM score > 0.4. However, the result is:

"There is no common residues in the input structures".

I don't know whether there is anything wrong with my input files, which are in PDB format. I attached them to this message.

I also tried the examples you illustrated on your website: "1C0F_S" and "1KCQ_A", but they have the same result as above.

I also tried TMscore_32 but got the same result as above.

Thank you very much for any help! I'm looking for your response!
