lmrcImageCTFCompensation(API)

DataManip/mrcImage/src/lmrcImageCTFCompensation is API to multiply CTF Correction to mrcImage. It is used by mrcImageCTFCompensation, mrcImageMultiCTFCompensation, and so on.

API

CTF Correction(One image)

extern void lmrcImageCTFCompensation(mrcImage* dstfft, ctfInfo* ctf, long mode);

Depending on ctf->flagAstigmatism, run different process. In addition, processes are changed by mode of argument. (refer ctfInfo(API))

Flag	Function Name	Description
true	ctfWeightForCorrection2D	CTF Correction(2D)
false	ctfWeightForCorrection	CTF Correction

If ctf->flagWin is true, perform other correction for each range R at the following rule.(sin Windowing)

Range	Description
ctf->CutLow or less	Directly
more than ctf->CutLow, and less than ctf->CutHigh	Weight = Weight*(cos((R-ctf->CutLow)/(ctf->CutHigh-ctf->CutLow)*M_PI)+1)*0.5;
more than ctf->CutHigh	0

CTF Correction(Multiple images)

extern void lmrcImageMultiCTFCompensation(mrcImage* dst, mrcImage* src, ctfInfo* ctf, long nfile, lmrcImageMultiCTFCompensationInfo info, long mode);

Depending on mode(&0xf), run either function at the following.

Value	Function Name	Description
+0	__lmrcImageMultiCTFCompensationMode0
+1	__lmrcImageMultiCTFCompensationMode1	Smoothing of Solvent

extern void __lmrcImageMultiCTFCompensationMode0(mrcImage* dst, mrcImage* src, ctfInfo* ctf, long nfile, lmrcImageMultiCTFCompensationInfo info, long mode);
extern void __lmrcImageMultiCTFCompensationMode1(mrcImage* dst, mrcImage* src, ctfInfo* ctf, long nfile, lmrcImageMultiCTFCompensationInfo info, long mode);

Output API Information

extern void lmrcImageMultiCTFCompensationUsage(FILE* fpt);
