Error Mesage- Graph mode

[Gabriel]

Hi,
i`m facing a problem when trying to run the Graph mode.
It always returns an error message:

Could you help me to figure out what`s happening?
Thanks!

The error message is consistent with a corrupted hexmap file.  But
we'll need to see the inputs to be sure.

[gabriel antunes daldegan]

Hi Carlos,

I cannot send you the ASCII files, cause they are too big.

Instead, I can send the original files (in GDB).

Sounds good?

Thanks

can you send the hexmap?
I am still unclear at what stage you are getting this error.

Sorry I`ve been not clear.

The error occurs when I set the Remnants.hxn at the Graph tab and click to run.

I changed the resolution of the raster (from 30m to 60m) and now the toolkit seems to be running well (it stills processing).

thanks

Hi Carlos, 

I`m still facing some problems trying to running the Graph tab for my Habitat file.

I`ve left it running for the last 4 days, and the toolkit seems to stoped the processing, but there is no graph file as output

I`m sending you my Habitat Hexmap by Large File Attachment website.

Could you check it, please?

Thank you!

Gabriel

Hi Carlos, good morning,

Please, find attached my habitat and cost hexmaps.

I`m still tryin to create the graphs files (LGFs and Edges), but it has been unsuccessful.

Thanks for your help!

The files you sent are not hexmaps but rather the ascii inputs, but I'll look at them.

2 questions:

1) what hexagon size are you specifiying when you create  the hexmap?

2) what type of graph file are you trying to create? you mention you are creating lgfs, but are you also trying to create an edgelist file?

(you realize that to create and edglist, you would just use the habitat hexmap, and not the cost hexmap).

thanks.

[gabriel antunes daldegan]

Oops,, sorry about that.

Now I`m sending the hexmaps.

They were created with 1 hectar size.

I`m trying to create diferents scenariso, so I`m running both LGFs (Direct and Undirect) and two Edge`s (distance and Conductance).

Thank you very much!

You're problem is that your hexagon size is too small given the extent
of the study region. Using 1 hectare hexagons creates a hexmap of 36
million hexagons (and thus 36 million nodes). Even if you could create
the graph file input, calculating centrality on a graph of this size
is not computationally feasible. You need to use larger hexagons.
Start with 100 hectare hexagons and then attempt eg, 50 hectare, 10
hectare, and see what you have patience to wait for. If these
resolutions do not capture the detail you need, you can try a nested
analysis (coarse-scale regional analysis followed by fine-scale
analysis on subregions).

Thank you very much Carlos.

I thought these could be the problem, but my supervisor told me to use the "best" resolution

now I have arguments to talk to him.

I`m creating bigger hexmap rigth now.

Thanks!

Have a good day

Hi Carlos,

I'm facing one more problem, these time trying  to run the final step at Connectivity tab.

Attached are two figures from the error.

I've tried to run diferents functions

thanks!

Can you post or send a portion (eg first 10 lines) of your input file
(dist.txt)?

Hi Carlos,

Attached is my graph input. which has generate the last error message.

I`m also sending one more image from another error message, which one I cannot understand, since my PC is running a 64bits system.

Thank you very much

2012/11/12 carlos <klamathco...@gmail.com>

[carlos]

hi, your problem is that the CAT expects decimal symbol to be in the
US convention ( a petiod: .) rather than the European convention (a
comma: ,). When I replace all commas with periods the input runs fine.
I am curious, why does the distance file contain commas? Was it
produced outside of the CAT? I would assume that a graph format file
produced within the CAT (with the "Graphs" tab) would always observe
the convention of using periods for decimals.

I don't have much to suggest on the windows error box as I cannot read
Portuguese :). If you are on a 64-bit system then you should be able
to use either version of the CAT.

Hi Carlos!

Thank you once again, your help has been great for me.

I`ve created the final file (Connectivity file), but is not in TXT format. I`ve tried to open it in ArcGIS, but the software doesn`t recognize the connectivity files. They`re attached in this message.

I`m now using ArcGIS 10, but I also have another PC with ArcGIS 9.3.

Best!

Gabriel

Those are text files. If you rename them to add a .txt extension, you
should be able to "relate" them to a shapefile in arcgis as described
in the manual.
Also, can you confirm whether the "connectivity" tab produces graph
format files with commas as the decimal separator on your system? If
so, we need to add code to the CAT that is aware of the differences
between "locales".
I cannot test this issue on my system.

Nice, I`ll try to open them in ArcGIS 9.3, because in ArcGIS 10 doesn`t recognize them.

In Brasil "Region" options are inverse from the US pattern, so my PC has comma for Decimals.

That`s why its generated the Graph files with commas and not periods.

So, I`ve changed the Region configuration in my pc, and now it`s working well.
