Minimum backbone RMSD values of the loops sampled by five different algorithms.

Minimum backbone RMSD values of the loops sampled by CCD, CSJD, SOS, FALCm and DiSGro for different loop structures. CCD result was obtained from Table 2 of Ref. [8]. CSJD result was obtained from Table 1 of Ref. [12]. SOS result was obtained from Table 1 of Ref. [18]. FALCm result was obtained from Table 2 of Ref. [22].

针对不同环结构，经CCD、CSJD、SOS、FALCm及DiSGro算法采样得到的环结构的主链均方根偏差（backbone RMSD）最小值。其中，CCD的结果取自文献[8]的表2，CSJD的结果取自文献[12]的表1，SOS的结果取自文献[18]的表1，FALCm的结果取自文献[22]的表2。
