Fig. 7From: Prediction of sensitivity to gefitinib/erlotinib for EGFR mutations in NSCLC based on structural interaction fingerprints and multilinear principal component analysisExample of normalizing the IFPs of three EGFR mutants to the same length by adding zeros. a For delE746_A750, 35 (5×7, where 7 means the 7 bits fingerprint for each residue) zeros are added between residues K745 and T751, due to the deletions of delE746_A750, 28 (4×7) zeros are added between residues A763 and Y764, due to the insertions of A763_Y764insFQEA, and 21 (3×7) zeros are added between residues V769 and D770, due to the insertions of V769_D770insASV. b For V769_D770insASV, 28 (4×7) zeros are added between residues A763 and Y764, due to the insertions of A763_Y764insFQEA. c For A763_Y764insFQEA, 21 (3×7) zeros are added between residues V769 and D770, due to the insertions of V769_D770insASVBack to article page
