Copy CTF parameters to re-imported particles?

I posted a similar question before, but never dare to try the method suggested

Import particle stack from Relion to CryoSPARC

Hi, I did 3D classification of a CryoSPARC created particle set in Relion3 and want to import the selected subset of particles back to CS for further processing. Although in the .star file the particle stack point to the original ones created by CS (in the JXXX folder), CS treats the imported particle stack as an independent one. There are two disadvantages: (1) In the subsequent processing, CS will make another copy of the original particle stack in /scratch (2) the imported stack loses some us…

I second that it would be very helpful to use particle location (_rlnCoordinateX and _rlnCoordinateY) to intersect the particle set.
