This might be a very simple question, but I am writing a little Macro for ImageJ and I cannot access the values in the Results log. Here is the code that does NOT work:
selectWindow("Results");
test=getResult("channel",0);
print("test");
Any tips on how this could be done? Thanks.
You were correct in pointing out that it might be due to a plugin not using the standard results table of ImageJ. The Color_Histogram plugin uses a non-standard way to report the results.
I filed a pull request on github.com that fixes this. When this pull request is merged and uploaded to the Fiji updater, the following macro code works as expected after running Analyze > Color Histogram:
test1 = getResultString("channel", 0);
print(test1);
test2 = getResult("mean", 0);
print(test2);

I am trying to run through open source Faster-RCNN code. Although I copied and pasted exact same code from the original, it doesn`t work.
I could not figure out what am I missing in order to run the code properly.
When I run this :
to validate class images...
test_loader = DataLoader(valid_dataset, batch_size = len(valid_dataset))
a,b,c = iter(test_loader).next()
print(torch.unique(c[0], return_counts=True))
Below response comes out :

I have a Tableau Workbook which connects to server-side data source. Researching online it seems the accepted way to refresh this is something like
tabcmd refreshextracts -–datasource “Number of Goals”.
My datasource is named "aggregated usage table". I have tried basically copying what I saw online, using
tabcmd refreshextracts -–datasource “aggregated usage table”, and receive the error message "*** Item not found". Clearly I am not correctly identifying my data source.
Can someone help me determine the correct syntax for this?
The O/E is Linux. Thank you!
Longshot, but something looks off about your dashes...
When I copy yours vs mine:
-– vs --
When I put yours into word and enlarge they look even weirder. Sometimes this can happen if copying and pasting from the web to import into your script.
Try copying and pasting my command and see if it works:
tabcmd refreshextracts --datasource “aggregated usage table”
I'm trying to write a macro to save preferences and read them after closing and reopening ImageJ.
The saving works, but the macro isn't reading the file. Moreover when I try to use one of these two lines an error occurs that the variable "Prefs" is unknown.
int myNumber = Prefs.get("my.persistent.number", 0);
Prefs.savePreferences();
What am I doing wrong? please help me :-)
The ImageJ macro language itself does not support storing custom preferences. (Only the set of built-in options (accessible via Edit > Options in the menu) can be saved, restored and adjusted.) You need to resort to calling the Java class via call("ij.Prefs.get", "my.persistent.number", "0");.
The following ImageJ macro works in an up-to-date Fiji/ImageJ installation:
myNumber = call("ij.Prefs.get", "my.persistent.number", "0");
print(myNumber);
call("ij.Prefs.set", "my.persistent.number", 3);
In the first run, it prints 0; every following run will print 3; after restarting Fiji, it will print 3 again. In case it does not work for you even after updating to the newest version, please report a bug via Help > Report a bug, which will also submit essential information about your installation to the developers to help them fix the issue.
Using one of the many scripting languages however, you can access the ij.Prefs java class directly, as you are trying to do it. Just do not forget to import the class before using it. This is an example Javascript:
importClass(Packages.ij.Prefs);
myNumber = Prefs.get("my.persistent.number", 0);
Prefs.set("my.persistent.number", myNumber);
Hope that helps.
I have a dicom from a GE MRI scanner and there are a few pieces of information in the header I require (namely the relative position of the scan). I tried using info = dicominfo(filename) but, for some reason, this piece of information does not show up. I know that this information is saved, however. It might be a private data, but I'm not completely sure. If anyone has any information on how to resolve this issue that would be greatly appreciated.
Try using the dicomread function instead, it should be more versatile than dicominfo and it reads the information files too. If this doesn't work then it means that the information you are trying to obtain is not made available by GE.
Or use gdcm to dump the private GE header:
$ gdcmdump --pdb input.dcm
I'm increasingly using cfscript, and like it where appropriately used.
One problem is that there doesn't appear to be any code assist for cfscript in CF Builder, so I find myself writing the tag of a function to leverage the code Assist, then converting to cfscript (which is silly).
For example:
addParam() is the cfscript equivalent of <cfqueryparam >. I get code assist when writing the the tag version, but not the script equivalent.
Does anyone know if there is a code assist library available for cfscript in cfBuilder? Or is this just a downside of working with cfscript?
Many Thanks in advance!

Your example is not using native CFScript, it's using the hack-solution Adobe provided for some shortcomings of CFScript's coverage of CF tags, which are implemented as a bunch of CFCs in the custom tags dir of your install. This stuff is not representative of CFML & its CFScript support as a whole.
I find that CFB gives hinting for most native functionality... is this not the case for you? What if you try listAppend() for example? Do you get code-assist for that?
UPDATE
I wonder if you get a warning in CFB on your line equivalent to this:
o = new Query();
? I do, by default. I have to make a link to the CustomTags/com dir, and then use this syntax:
o = new com.adobe.Query();
Then I don't get a warning, and indeed I get the code assist you're expecting. I cannot get it to give me hinting on just the non-qualified path to Query.cfc though.
Not ideal. Or maybe I'm missing something, too.
