I have been trying to use the IsoParamterization filters in Meshlab 1.3.0 in Windows. All the filters seem to work with the exception of the IsoParameterization Transfer one. I always get an error message that the "Source Mesh does not have an Abstract Parameterization" and it suggests I run the IsoParameterization filter. Note that I have tried this with a source mesh which has just successfully completed a IsoParameterization, and have successfully saved the .abs file. I have also tried reloading the IsoParameterization (which also works), but again the transfer fails. I have tried this with my own meshes and with meshes that I downloaded from MeshLab with IsoParameterization examples (e.g. the bunny). It seems to fail immediately as if it can't properly detect the flag that identifies a mesh with an IsoParameterization. I tried this also with v 1.2.3a and got the same error.
