I am currently performing a variable cell relaxation (vc-relax) calculation for Li2S6. However, I keep encountering the error message: "Not enough space allocated for radial FFT: try restarting with a larger cell_factor." According to the documentation, the
recommended values for cell_factor during the pw.x execution are 2 or 1. Despite trying both values, the error persists. Interestingly, when I set cell_factor to 3, the calculation proceeds without any issues.</div>

Could you please advise if setting the cell_factor to 3 is appropriate for pw.x, or if there might be an underlying issue with my parameters?</div>
