Re: [Ifeffit] XAS viewer unit detection during data reading

2023-02-28 Thread Matt Newville 
Hi Siebe,

Just to agree with Edmund and Mauro:  selecting "energy" and changing data
type from "raw" to "XAS" should help.  But, you would have to do this for
every file, which is not ideal.

The file reader is trying to guess whether data is in energy (and if so,
what units are used) and whether it is really XAS data or some other kind
of data. I suspect that it is defaulting to "raw" because the energy column
is not labeled "energy", but "col1" -- it sort of looks like the reader is
not doing a good job of guessing what the columns mean.

Posting a file would help diagnose why it is guessing wrong.  The file
reading does try to guess what beamline a data file came from, so if you
send a file, maybe we can add enough hints for files from that beamline to
work more reliably.

Re: [Ifeffit] XAS viewer unit detection during data reading

2023-02-28 Thread Mauro ROVEZZI 

Dear Siebe,

In addition to the quick workaround suggested by Edmund, if you could 
send your data file to me (here or by private email), I could have a 
look why xas_viewer is not detecting the energy scale automatically.


@Edmund, usually the "xas" file type is setted automatically when the 
x-axis is identified as energy scale in the `read_ascii` function. If 
you have data files that are not detected correctly as XAS data files, 
please, do not hesitate to send them to us.


Best,
Mauro

Dear all,
I am not sure if this mailing list is the correct medium for this 
question. Apologies, if not.


I am looking to import files in XAS viewer, which worked fine in ATHENA, 
but in XAS viewer the correct units of the data are not detected and I 
cannot manually change them. I can get a plot of the data, but the data 
is not recognized by the software as XAS data, i.e. a lot of 
plotting/conversion options do not show.


I hope the following screenshots provide sufficient information to 
illustrate my issue.


Reading in a .dat file of fluorescence data. I can't change the units in 
the marked area.

The data can be read into the XAS viewer, but I don't have the regular 
plotting options in these dropdown menus.

Any advice would be much appreciated.

Re: [Ifeffit] XAS viewer unit detection during data reading

2023-02-28 Thread Welter, Edmund 
Dear Siebe, 

did you try to change the data type from "raw" to XAS. If you click on the 
small arrow on the right you should have the choice between xas and raw. On my 
computer that works and after that I can choose the unit for the X-axis. For 
some reason "raw" seems to be the preset choice. Maybe Matt could change that, 
I fell into this trap several times. 

Cheers, 
Edmund

Dear all, 
I am not sure if this mailing list is the correct medium for this question. 
Apologies, if not. 

I am looking to import files in XAS viewer, which worked fine in ATHENA, but in 
XAS viewer the correct units of the data are not detected and I cannot manually 
change them. I can get a plot of the data, but the data is not recognized by 
the software as XAS data, i.e. a lot of plotting/conversion options do not 
show. 

I hope the following screenshots provide sufficient information to illustrate 
my issue. 

Reading in a .dat file of fluorescence data. I can't change the units in the 
marked area. 



The data can be read into the XAS viewer, but I don't have the regular plotting 
options in these dropdown menus. 



Any advice would be much appreciated. 

Kind regards,
