Hi Kavya,

21824 is the time in ps at which the two atoms indicated, 2062 and
3688, are at the short distance given. You can dump the frame with
trjconv and have a look. Probably your molecule stretched, or you
solvated in a rectangular box and the protein rotated. In the first
case, set a larger distance, in the second, use a rhombic
