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?


You can change the file extension from MET Files (*.met) to All files (*.*)

and then choose the MTL.txt file from the available files

I am using QGIS 3.4.5.

    I edited my original post (image 2). I do not have the option to select "All files(.)" – Zman3 Jul 1 '19 at 5:27
  • @Zman3 Try to use QGIS 3.4.9 LTR maybe it will solve the issue. – ahmadhanb Jul 1 '19 at 8:11
  • I just did, and I can get to the file, but there is still an error with the file. See additional edits. – Zman3 Jul 1 '19 at 8:14
  • QGIS 3.10 - select *MTL.txt or *.* option is missing – Mr. Che Dec 16 '19 at 6:15
