Re^4: 2d Scan using RSURFACE version 7.1.G Build 5618 Firefly running on Linux

Peter Jarowski


Thanks for your help. In order to isolate the problem I have been trying ethene instead. I have gone back to using the zmat. However, the results are weird. If I can get this simple case to work I might have shot at something more complex. The attached file basically completes without error but the first step steps the central bond to 2.6 A for no reason. The correct numbers are reported in the final summary. I just don't understand.

Your help would be much appreciated.

Also, if you could help me translate this example into dlc that would be great. There is not that much in this forum about 2D scans.
