<font size="-1">Perhaps have isolated the problem.<br>
<br>
I haven't checked output in detail yet, but looks like the
procedure has worked with only changing blc,trc before running
DOFARS. </font><br>
<font size="-1">in the run that failed, i set blc, trc to </font><small>3341
3361; 5421 5601 before running DOFARS. when it actually gets to
the FARS stage, DOFARS apparently has set the BLC, TRC to 1 0 0, 1
0 0. the output maps have the correct dimensions<br>
301,2081,1941 , but the output is garbage.<br>
<br>
if instead i set original blc, trc to 0,0, then when DOFARS gets
to the FARS stage, it has blc,trc 0,0</small><br>
