dear all,

I got an error message when i try to mosaic images :

Mosaicing 2 images…
syntax error, unexpected INTEGER, expecting VARNAME or NAME
Parse error
ERROR: parse error
ERROR: An error occurred while running r.mapcalc

the syntax error is also appeared when i try to execute r.mapcalc, both using GUI and terminal. Seems the error occurred after i upgraded grass from 7.0.3 to 7.0.4. I hope someone can help, thank you in advance

Hi Helmut,

the r.mapcalc error i found at the first time when i try to mosaic two images. Then I try r.mapcalc in another operation, for example :

r.mapcalc “image 1 = if( NDVI@220215 >= 0.25 ,1 ,0)”
syntax error, unexpected INTEGER, expecting ‘(’
Parse error
ERROR: parse error

regards,

Andry

Hei Andy,

You have a whitespace in your mapname, wich is not valid. I am surprised that a mapset name with only numbers is allowed…

The rest looks OK.

Try:

r.mapcalc expression=“image1=if( NDVI@220215 >= 0.25 ,1 ,0)”

instead.

Cheers

Stefan

A user got the same problem last year, in the end it was the usage or
a restricted character in location/mapset name.
Please see

(esp. the second part of that email).

r.mapcalc "image 1 = if( NDVI@220215 >= 0.25 ,1 ,0)"
syntax error, unexpected INTEGER, expecting '('

is there a whitespace between "image" and "1"?

try image1 instead of image 1.

try image1 instead of image 1.

just tried it here:

r.mapcalc expression=image 1 = elevation@PERMANENT
syntax error, unexpected INTEGER, expecting '('
Parse error
ERROR: parse error

white spaces are not allowed in layer names.

Dear All,

Thanks for all your corrections, indeed i made mistakes in mapset name (only use numbers without any characters) and whitespace in the new map name. Now its solved, thanks again.

regards,

Andry

Hi,

Same problem.

Solution is to eliminate the reference to the mapset (i.e. MyMap@mapset -->
MyMap )
