[Wien] treshold in rstruc.f

2013-04-03 Thread Stefaan Cottenier
The case.struct that is pasted hereafter leads to a 'negative position in rstruc. Please report.' error. There is indeed a slightly negative value (-7e-7) generated by atom Si7 in case.outputs. 'x patchsymm' leads to very small numbers (1e-15 to 1e-16), which -- if I interpret that output

For the moment, adjusting the threshold should be fine. There seems nothing wrong in the input (struct file) and the original positions are valid positions. I'll look into some more details in the code. Am 03.04.2013 22:01, schrieb Stefaan Cottenier: FYI, probably you have to slightly
