image processing - ArcPy Python script - Runtime Error: ERROR 010240: could not save raster dataset to C:\L_B2dpy with output format GRID -

-

i m working on script python , arcpy process landsat satellite images. near end of script of error @ same location each time. error occurs after 1 successful run of code (i.e. error occurs on second occurrence of same task)

print "starting rt_b2dpy (2 of 4)" if arcpy.exists(rt_b2dpy):     arcpy.delete_management(rt_b2dpy) rt_b2dpy = rt2 - 1 rt_b2dpy.save("rt_b2dpy") print "rt_b2dpy has been created"

i have env.overwriteoutput set true not problem.

i gave code friend run , got process 4 occurrences of block of code output blank. used there modified script (change path entries)and got error @ same location first one:

exceptions.eoferror:[errno 10054] existing connection forcibly closed remote host

this error crashed python , editor.

the script produces grid first run, second 1 creates grid unreadable in arcgis.

i m working windows virtual machine (parallels) on mac 8 gb of ram. virtual machine using 4 gb of ram.

i have not clue going on or how debug it! appreciated.

workaround = found work around saving output tif image rather raster file.

just make sure obvious things aren't problem:

1) have set arcpy.env.workspace, arcpy.env.scratchworkspace? presuming outside gdb, don't need arcpy.env.scratchfolder set (only applies in arcgis 10.1+, think).

2) there enough disk space? i've gotten not-so-helpful message "forcible" close when i've run out of space.

3) bit of voodoo, maybe specify pathname output save, instead of local name show in snippet.

plot - Remove Objects from Legend When You Have Also Used Fit, Matlab -

Image
i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
