3 months ago Please make sure that the path is to the files and/or names are properly written, is there a PH00.fits file in that directory?. If that doesn't work it might be a permissions problem. Type: chmod 777 * .Run again. If the problem persists, start a new directory and follow the linked analysis thread to perform a different check https://fermi.gsfc.nasa.gov/ssc/data/analysis/scitools/binned_likelihood_tutorial.html
When I use "gtselsct" to merge data from multiple fits files, ".txt "there are fits files in the document and the current directory, but "file not found" is displayed. How can I solve it?
