Comparison of FASPR with four popular side-chain packing programs on the I-TASSER-modeled structures from DB379, where bold fonts mark the best performer in each category

Method	${\mathrm{\chi }}_{1 - 4}$ recovery rate (%)a			#Clash
	All	Core	Surface
FASPR	58.0	70.9	44.0	397
CISRR	57.1	70.7	42.5	224
RASP	55.9	68.4	42.8	1633

^aThe ${\mathrm{\chi }}_{1 - 4}$ recovery rate was calculated between the 379 repacked models based on I-TASSER main chains and the native structures. Since the I-TASSER models have different main-chain positions compared to the native structures, the side-chain RMSD values were not calculated.
