Why my opensees cannot read the file containing the load factors values correctly when I use it to do a quasi-static ana

Why my opensees cannot read the file containing the load factors values correctly when I use it to do a quasi-static analysis of a column? The results after the run are empty? :?
Is it that the command not written right?
#timeSeries Path 1 -dt 0.1 -filePath jiazai.txt
Here is the modelling code for a certain column, but I cannot obtain a correct results:
#
