Hi Frank,

Xianfang said that the out of memory message came during the 
triangulation stage of denoising.  The triangulation is carried out by 
triangle.c, which he did not write.  I don't know how triangle uses 
memory.  Perhaps Hamish does?

Xianfang also recommended denoising small areas, perhaps with overlap, 
and seeing how well they can be merged.

Cheers

John
