SweeD does not report correct CLR for folded spectra

[oneoverx]

Hello,
SweeD does not output a correct CLR (and probably alpha) for folded spectra as in the following example of a simulated strong sweep:

Output SweeD:

The input file was in the Sweepfinder format, but 'ms' format yields the same problem. I tried version 3.2.1 and 4.0.0 of SweeD.

If the same input data is characterized as unfolded, (a zero instead of a 1 in the last column) both tools yield very similar results. Applying command line option "-folded" instead of marking the status in the file makes no difference.

I guuess this is a bug and not a feature...
