Dear all, I am using artemis from Demeter and I am unable to "change the current data file (that is, to apply this fitting model to a different data set)" as it was possible with the "open file" function of the old artemis. This function openned a popup window asking to choose between "read a new data file" or "change the current data file". If I use the "open project or data" function of Dartemis (or the "Add" button of the "Data sets" frame), it opens the data set in a new window. Then, I am unable to use the paths and parameters used for the previous fit. Any attemp to export, transfer or drag/drop paths or parameters has either no effect or crashes the program. If I use the "Replace this chi(k)" function, it automatically chooses to "read a new data file (that is, to do multiple data set fitting)" without opening any popup window asking my choice. I suppose I did not find the good way to apply my fitting model to a new data set. Thank you for advice.
