The missing feff paths
Hi, I have a problem when I used Demeter 9.18 or 9.20. The Artemis window only show parts of the calculated feff paths such as the followed figure (only 0, 4, 5, 6, 7, 10 paths of the first 10 paths were shown, and where is the other paths?). Did anyone meet this problem and how did you treat it? Many thanks! best regards, Qiantao Shi Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences
This is not a problem -- it is the intended behavior of Artemis. Look at the attached screenshot. This explains something that doesn't seem to be covered in the document. There is a configuration parameter which Artemis uses in an attempt to restrict the paths displayed to only those that are likely to have any impact on the fit. By default, Artemis simply does not display any paths with a ranking (i.e. an estimate of importance) smaller than 3. That is configurable. If you set it to zero, no paths will be dropped. This is also relevant to the behavior of the path finder: http://bruceravel.github.io/demeter/artug/extended/fuzzy.html HTH, B On 08/14/2014 04:45 AM, 史乾涛 wrote:

Actually, I see that this is mentioned briefly at the end of this section of the Artemis document: http://bruceravel.github.io/demeter/artug/feff/paths.html#pathplottingandpat...

Got it. Thanks very much! Best regards, Qiantao Shi
