[Ifeffit] Fwd: Re: Demeter deglitch problem

I'm sorry, Sathish, but I simply don't see this behavior, on any of
the computers I have tried.

I have no trouble putting the cursor on the point in question.  It can
be a little tricky getting the cursor on, for example, one of the
points from 6750 to 6770.  That is because of the details of the
algorithm that tries to find the actual data point that is closest to
whatever point was clicked on.  For a data point that is not a distant
outlier, pretty good aim is required.

That said, the two points near 6864 are distant outliers.  Hitting one
and not the other might be hard, but hitting one of them is easy.

I am not disputing that you are having trouble.  I am just saying that
given the data you sent and the explanation you gave, I cannot
reproduce the behavior, so I don't know what I can do to help.

Dear Bruce

Thanks a lot for your time.

I am sorry, I am a beginner in the field of XAS, thus was confused.

Please find the attachment of one of my glitch data and an image showing
the randomly chosen point at 6705 eV by software even though i double
clicked at 6864 eV and in addition, I cannot move the position of
randomly chosen point.

I have tried both in my windows laptop and PC, it does not work in both
cases. I hope this time I have provided the details you expected?

         I am sorry to contact you here, I watched your whole XAS
         workshop 2011
         at Diamond, it was very helpful.

         Regarding the problem, I could not understand your message, I
         read the
         link to reports bug, I understand you cannot reproduce my
         problem also,
         I just wanted to know, if anybody had same problem like me and
         have any

         I am just wondering, does your message also means that I should
         send the
         rawdata or print screen?


     Look, I'm happy to help, but you have to give me something to work
     with.  Obviously, I think deglitching works, otherwise I would have
     said something different.

     If you cannot give me some way of reproducing what you see on one my
     own computers, there is no way that I can help you.  I'm not asking
     for a differently detailed explanation, I am asking for data and a
     recipe that reproduces the problem.  Without that, what could I
     possibly do to help?
