Hola Verooooo! Thanks you for answer! I'm working to solve it. Apparently all my imported rasters are zero cell values. There is something wrong with my gdalwarp command... I'll tell you later... Thanks!!!

I'm so glad you are using grass and writing to the list! :) Markus won me, but I had the same pieces of advice. First idea/advice: do not use folder names (nor file names) with spaces, second: maybe you wanna update to 7.0.4, the new stable release. I've tried here (grass71, fedora23 box) with: t.rast.export input=cla@clorofila output=cla.gzip compression=gzip directory=/home/veroandreo where="start_time >= '2013-01-01'" Checking GDAL data type and nodata value... 100%Using GDAL data type <Float32>Input raster map contains cells with NULL-value (no-data). The value -nanwill be used to represent no-data values in the input map. You can specifya nodata value with the nodata option.Exporting raster data to GTiff format... 100%r.out.gdal complete. File <A20130012013008.L3m_8D_CHL_chlor_a_4km_arg.tif>created....tar xvf cla.gzip all is there and looks fine... The nodata option comes from r.out.gdal [1]. t.rast.export uses it to export maps in the strds. Don't know about gdalwarp, but in any case, if you will then import data into R for other analyses, you can change the value there.

I think I made a mistake when sent the message yesterday... I was construct a strds in grass 7.0.3, and I want to export it for use in R to do some statistics not included with tgrass.. But when I do the export operation, I receive this message: Usising the GUI: t.rast.export --overwrite --verbose input=LST2@MOD11A2 output=C:\SIG\Base de datos area de estudio\Datasets_R\LSR_R compression=gzipTraceback (most recent call last): File "C:\OSGEO4~1\apps\grass\grass-7.0.3/scripts/t.rast.export.py", line 87, in <module> main() File "C:\OSGEO4~1\apps\grass\grass-7.0.3/scripts/t.rast.export.py", line 82, in main _input, output, compression, directory, where, _format,"strds") File "C:\OSGEO4~1\apps\grass\grass-7.0.3\etc\python\grass\temporal\stds_export.py", line 268, in export_stds new_cwd = tempfile.mkdtemp(dir=directory) File "C:\OSGEO4~1\apps\Python27\lib\tempfile.py", line329, in mkdtemp _os.mkdir(file, 0700)WindowsError: [Error 3] El sistema no puede encontrar laruta especificada: '/tmp\\tmppi2oh1'(Wed May 04 16:09:44 2016) Comando finalizado.

I was try to set the nodata values to 0 using gdalwarp but this doesn't work apparently... Thanks you!!
