I have a new idea. I've just compiled the healpix soft and generated a map from previously calculated power spectrum from new cmbfast package.

eg. see http://adjani.astro.uni.torun.pl/~blew/praca/topology/moj-l04-08-anim.gif or if it's too slow moj-l04-08-anim2.gif :))

I was just thinking about that tast of significance of the signal you've found and what you said that this is a lot of work doesn's seem to be right to me now. well imagine I provide you a new simulated map. in fits format for standard LCDM WMAP model in WMAP resolution and pixelisation scheme. you put this through you pileline for dodec just to see what comes out. the rms signal or peak-to-peak dispersion would define the valid detection threshold for the real map. isn't that right ?

it doesn't matter that the simulation is performed for simply connected space. - even better. in fact it's similar as doing the same thing but on the realmap but with nonphysical case of zero rotation.

I'll try to do it tommorow on my own with your package if I'll manage to find out how it works and compile it correctly.

what do you think. of couser to treat this seriously I must pay more attention to noise thing in each pixel, size of beam etc but as I remember I read some good publication about this stuff recently so perhaps this isn't big problem.

the bigger problem could possibly arise when I'd like to simulate the map for some non-trivial topology to get some strong signal in a shape of spikes in circles correlation function, like cornish et al. did.
