<div>Hello list,</div>
<div> </div>
<div>after the prior process of getting 2gb data conversion using gdal with grass61cvs been a success. </div>
<div> </div>
<div>i am facing a problem with terraflow process on the 2gb dataset(ESRI Ascii Raster Grid) which i converted to grass raster grid file. </div>
