Problem with average command in argyll?
« on: May 03, 2010, 04:45:12 pm »

Wondering if anyone can verify this for me? I'm trying to average several measurement files using the average command in Argyll. That seems to go just fine however when I try to generate a profile using colprof I get the following error:

colprof: Error - Input file doesn't contain field SPEC_000

The original measurement files were from the Measure Tool in Profile Maker and were converted to ti3 files using txt2ti3. I have no problem generating an ICC profile from one of the converted ti3 files but when I average two of them together and try to generate a profile I get the above error. This is with the OS X version.

Cheers, Joe

Did you try to use free ColorLab tool to average the measurements?

Thanks, hadn't seen that before.

Doesn't seem to work under 10.6.3. It launched but it doesn't do anything... for example, if I open a few measurement files and select the compare feature they show up in the pull down menu but the comparison values don't change. They stay grayed out. When you select averaging, nothing happens.

Cheers, Joe

I had no problem using the average command to average two sets of data from chartread using Argyll 1.0.3 on Windows XP Pro.

I have been using Argyll CMS to make printer profiles using a Datacolor (Colorvision) Spectro.
I seem to get better profiles from the Argyll software than using Spyder3Print.  I am using them with a Canon 9500.

The incantations looked like this:  9500 is the base file name for this example - modify to suit
The working directory is C:\Argyll_CMS\Argyll_V1.0.3\work.
The Argyll executables (exe files) are in C:\Argyll_CMS\Argyll_V1.0.3\bin  

Commands used to generate the target tiff files:
This generates 504 patches on two LTR or art LTR sheets

To generate the target data:
C:\Argyll_CMS\Argyll_V1.0.3\work>..\bin\targen -v -d3 -f504 9500

To generate the target tiff file:
C:\Argyll_CMS\Argyll_V1.0.3\work>..\bin\printtarg -v -iSS -pLetterR -a2 -T 9500
Paper chosen is LetterR [279.4 x 215.9 mm]
Patches = 504
Test patches per row = 14
Rows per page = 18, patches per page = 252
Rows in last strip = 18, patches in last row = 14
Total pages needed = 2

Target were printed from CS4 with “printer manages color”
Printer was configured for manual “none”
Media selection must be appropriate for paper.  For a Canon 9500 use the fine art media settings to get a good Dmax on matte paper.

Reading patches:

Patches were read into file using spectro triggered by CR (more reliable than button)
File was checked with text editor to confirm number of lines and make sure patches were read.
A “d” command was added at end of the data file (text editor) – otherwise chartread goes into infinite loop

Chartread command:  chartread –xl 9500 < 9500_value.txt

Generating profile file:

C:\Argyll_CMS\Argyll_V1.0.3\work>..\bin\colprof -v -D"9500" -qm -S ProPhoto.icm -cmt -dpp 9500

I also made profiles using sRGB and Adobe icm files as the "source" color space.  I don't think it makes much difference.

Thanks Sam!

The problem at this point doesn't seem to be with the average tool itself, it may be in the txt2ti3 tool which I'm using to convert the XRite Measure Tool generated measurement files to the Argyll ti3 format. I posted on the Argyll CMS list and I think Graeme is having a look. If anyone would like to try converting my files to ti3 (or averaging my ti3 files) here's a link to the files as well as what I posted to the Argyll mailing list:

Here's a link to the txt files and the converted ti3 files

http://www.symphonyphoto.com/argyllcms/measurementFiles.zip

The command arguments I'm using with average are:

average CM_Silver_Rag_918_1.ti3 CM_Silver_Rag_918_2.ti3 average.ti3

And then after that...

colprof average

Colprof returns the error: "colprof: Error - Input file doesn't contain field SPEC_000"

Aside from that... Sam, thanks for the quick run down on Argyll. I was just reading through the command line arguments as I figured I'd try generating some targets via Argyll, print them, read 'em in and average them. You just saved me a whole bunch of time reading through the manual!!!!! :-)

Sam,

Quick question, on the targen command wouldn't you want 2 for the -d argument (generating for print not video?)...

So it would look like this...

targen -v -d2 -f[number_of_patches] [filename]
