I am having an issue with GRASS i.landsat.toar tool. It will not let me choose my metadata .txt file. I click on the three dots to the right of "Name of Landsat metadata file (.met or MTL.txt) [optional]" (image 1). I browse to where my metadata is stored (image 2), but it is not there. The only option for file selection is .met. I look in my folder and the MTL.txt file is clearly there (image 3). I do not understand why QGIS will not let me pick the .txt file type (image 2)? I am using QGIS 3.6.3 with GRASS 7.6.1
I installed QGIS 3.4.9 with GRASS 7.6.1 and was able to select all files to grab the MTL.txt file. Though I recieve the error "Wrong or missing parameter value: Name of Landsat metadata file (.met or MTL.txt)". So it seems that it is not reading my MTL.txt file correctly?
