Hi guys, I have experienced the problem with file saving on the two updates from last week.
During calibration (flat file), the calibrated sub-flats were stored where I wanted. Then the combined master flat- the process of saving the file into the specified folder was extremelly slow, about one minute at least (16mb). When i wanted to select the master flat for the light calibration, the file was not displayed available in the folder. But when I did try to OPEN the file normally in Pixi, the file was right there in the folder.
Another issue- when i then selected only one flat for calibration, and did calibrate set of lights just to see my flats were correct, they were written into the specified file with _c suffix as I specified, but when I did ask Pixi to register stars, the_r files were not created despite specified (or again remained unbisible), only _c files were in the folder.
I want to add that never before i had this kind of issue with older pixi versions.
Thanks for the advice, I have pretty nice set of data from last night at Izana mountain in Tenerife, and can ´t wait to see..
