Failure to (1) extract raster dataset by attributes and (2) convert ASCII to raster

Discussion created by sdalsal on Mar 22, 2014
Hi everyone,
I have a raster dataset  (NLCD2006 Land Cover raster from http://www.mrlc.gov/nlcd06_data.php) that I am working with to extract the portion of it using the extract by attributes in the spatial analyst. My goal is to create a raster dataset that includes the Values :21,22,23,24,25,81,and 82. I received error messages using this method. Out of 290 rows in the raster dataset, I only need 7 rows.

So I tried another way, I selected the rows and created a dataset in ASCII format, hoping to convert the ASCII to raster. I received error messages using that method as well.

I would appreciate it if you can point to what I may be doing wrong or direct me to a better way of creating this raster dataset that includes only 7 rows. I also attached some screenshots as well just to give you an idea.

Thanks for your help in advance.
