Auto Close after OK

[HanniYolina]

I tried using GFA, but after i clicked OK, QGIS auto close.
My data size is only 1kb.
How to solve this?

Hi HanniYolina. I experienced the same. I think it is a problem regarding the "noData" values. My work around was to convert the "noData" values to -9999 (using the r.null function from GRASS.---- using Hannover version of QGIS).-- but this slightly changed the resolution, so I used the warp function to resample back to the original resolution.

Thank you yukis84. I already convert the "noData" values to -9999 but still auto close. Then i tried another QGiS version. I tried using QGIS 2.6 and it works.
But there is an error "IOError: [Errno 9] Bad file descriptor" in line 950 of doGeomorphicFloodIndex.py and GFA stopped at 99%.
