Q: I want to manually edit measurement list files. Is that okay?

A: That's perfectly fine. There are two important things to note here:

• Please note that there is way to modify entries of the measurement list during creation by injecting code into the function "custom_func" of the script for creating measurement lists. This method could avoid repetition of work and improved reproducibility
• The values in columns specified in the variable "overwrite_old_values" of the list creation script will be retained from existing files. This is a mechanism to ensure that any hand-written entries in list files do not get overwritten when a list file is recreated. Please make sure that the name of the column you manually edited is included in this variable.

Q: Why can't I load all rows of a measurement list for FURA data in VIEW-gui when LE_loadExp is set to 4?

A: When a measurement is loaded in VIEW_gui with LE_loadExp set to 4, VIEW tries to load the data indicated by the entry in the column "dbb2" in addition to the data indicated by the entry in the column "dbb1". Since the rows for 380nm do not have "dbb2" entries, there is an error saying "none.inf/pst" were not found. Load the rows for 340nm to load 340nm data into raw1, 380nm data in raw2 and ratio to sig1.

Q: I created measurement lists using editing the template provided. Should I worry about the warnings thrown in terminal?

A: If the warning complains about not being able to find a specific file, then double check that this file exists. If the warning is about not being able to find "none", then ignore it.

Q: I am trying to use CTV 0/1/303/333 and I get an error.

A: These CTVs can only be used when stimulus information has been specified in the list file (guide). The recommended way is to modify the function "custom_func" in your script for creating measurement lists ("create_measurement_list.py") to specify values of columns related to stimulus specification. Another way is to add these columns manually after the measurement lists have been created.

Q: In ILTIS, I am not able to create a ROI with ROI type "polygon-multiclick"? A: Every click creates a vertex of the polygon. Once you have finished choosing all the vertices, click INSIDE the small circle around "vertex 1" to complete the polygon and create it
