Fmask Error: output argument "clr_pct"...

[nasavish]

Downloaded the standalone Fmask for windows and are having some issue. The package came with the following files:

After being prompted to install the MCR package, which successfully occurred, we tried running the Fmask. This is the error we received:

Anyone know what is going on? The reason we are using Fmask is because it masks out cloud shadows, which the cloudmask script on dnppy does not.

Are you calling fmask from the command line? or no?

EDIT: If so, how do you call it?

[nasavish]

No. We have been trying to open the application from the file folder. I did see this thread online...

Where is your data? from a quick google search it looks like you'll need to call it from your cline

---

Say:

• Your data is in C:/data/
• Fmask is in C:/tools/

Open your command prompt

> cd C:/data
> C:/tools/Fmask

Try that

In the case of that issue, it was because he needed to change drives as well while calling Fmask (thus the need for \D), I don't believe that is the case for you (unless your data is on an external harddrive)

I am going to write what I understand your suggestion to mean.

1. Change directory of file path to where data is located
2. Call file path where Fmask is located.

I have attached images of what happened when I tried doing that.

First image is of (1) after pressing 'enter'

This image is of (2) before pressing 'enter'

This image is of (2) after pressing 'enter'

After this step, as you can see from the image, I am receiving an error. Have I done something incorrectly? Also, I'm not sure I completely understand (2) of your instructions. Can you please elaborate?

try Fmask.exe , the extension is important if it's included in the name.

[nasavish]

Receiving the same error.

However, I just realized that this computer doesn't have the hardware required to support Fmask.

Let me give this a go on one of the other computers that is all set up.

[nasavish]

No go

I tried opening the Fmask application again and, while the same error popped up as in the first post, this error followed.

[Syntaf]

Is desktop/Fmask Fmask.exe , or the folder containing Fmask.exe? you cannot launch a folder via the command line, you need to launch an executable .

[nasavish]

It was referring to the folder. I just tried modifying it so it would launch the application but perhaps I did it incorrectly because I am getting the same error.

[Syntaf]

That's because your command line is parsing C:\Users\NASA DEVELOP\Desktop\Trial\Fmask\Fmask.exe as two separate commands due to the space . Place this in "" quotes so the cmd knows this is one single path

As a note: this issue has nothing to do with dnppy, so i've added the wontfix label.
