During structure refinement, relatively intense periodic electron density Q-peaks appear along the bonds between atoms. What do they imply and how to go around them ?
Typically, one will be able to see residual Q peaks appearing along the bonds if the crystal is strongly diffracting (electron density of the bonds). What is "relatively intense" in terms of the Q-peak height? In addition, what are the atoms? If it is a particularly "heavy" atom, then residual electron density can be expected. e.g. Ir metal complex with Q-peaks ~1-2 in height near Ir atom.
The max height is 7 for Q peaks residing around Pb atoms and around 4 for those next to I atoms.
This might suggest that you have some disorder in your structure. You should look at the ellipsoids of your heavy atoms, if they are particularly elongated towards these large Q peaks, disorder is very likely.
High Q peaks around heavy atoms can also result from a not accurate enough absorption correction.
