API

CTF推定

Calculate average phase difference between Input in(FFT) and Reference ref(FFT), then Output the minimum data to linfo->minResidual(Def, Ratio), and the distribution to linfo->Dif.

extern void lmrcImageCTFDetermination (lmrcImageCTFDeterminationInfo *linfo, 
									   lmrcImageCTFDeterminationInfoRef *refinfo,
							 	        mrcImage* in, mrcImage* ref,
									   lmrcImageCTFDeterminationInfoMode *Mode);

Calculate CTF depending on phase difference between Input in(FFT) and Reference ref(FFT), then output it to linfo->resFFT.

extern void lmrcImageCTFDeterminationResultFFT (lmrcImageCTFDeterminationInfo *linfo, 
									    		lmrcImageCTFDeterminationInfoRef *refinfo,
							 	        	     mrcImage* in, mrcImage* ref,
									   			lmrcImageCTFDeterminationInfoMode *Mode);

Calculate weight

Output the weight between input image and reference image depending on mode.

extern double MagWeightForCTFDetermine(double inMag, double refMag, 
									 long mode); 

mode	method of weight
0	1
1	(inMag + refMag)/2
