Description
I have a problem while using gdal_merge from Raster>Miscellanious>Merge
While setting No data value the result comes out with the no data. So my value ranges from -9999 to 54.8
The correct value is -1.2 to 54.8
Using Weekly from december 2. 2013

What is the nodata value you are using, is it -9999 ?
Can you try to add the following to the command (by clicking on the pencil icon)
-a_nodata -9999
I have made a pull request [1] to fix a similar issue reported on the mailing list [2]
