Hey, I would some assitance, I wrote this code to find the average between the max and the min and assign that value to the nan, nut i have to chnage up my code, to assign the NaN to the previous non-zero value.
Example 112 113 114 116 NaN would be 112 113 114 116 116.
Text.txt
112 113 114 116 NaN 112 119 109 117 NaN
115 117 116 101 110 Nan 112 118 120 NaN
