e6cphdrs 0.1 © 2004 by Turku PET Center Copies all mainheader and subheader contents from one CTI ECAT 6.3 file to another. Only header fileds that affect the quantitation directly (calibration coefficients and scale factors) are not copied. Files must be of the same type, and they must have the same matrices. Usage: e6cphdrs <file to copy from> <file to copy to> Note that program edits the copy-to -file without making any backup!
