Hi Aishwarya, besides distances, the only other physical quantities that enter into the calculation of moments of inertia are the masses of the particles, so looking only at the apparent radius at VMD is not enough to say anything about your results. so either your systems are indeed different an

Hi, Yes of course the ratios are similar. The shapes are similar But when I measure the distance of the two agrregates in VMD , the length of the aggregates and the width of the aggregates are more or less of the same dimensions. Which means that the size of the aggregates are comparable and there

Solution to what exactly? Both sets have a ~1:3:3 ratio, I'd guess you have two prolate spheroids? and it indicates that yes, they have a similar shape as you stated. Or is the concern the fact that there is ~4x difference between agg1 and agg2 I values? That indicates that agg1 is bigger than a
