Last change on this file since 339 was 332, checked in by sommeria, 13 years ago

NomType? changed from _i1-i2 ... to _1-2 ... (bugs to be expected!)
bug corrected in geometry_calib
series changed by introducing a from FileIndices?, introduction of find_file_series to detect the file series corresponding to an input file
