@jctay,
@pharmacist, ChromIQ 4.3.33 is out:
https://github.com/itsab1989/ChromIQ/releases/tag/v4.3.33
This post has four parts: the patch names in the .txf, a new lights option for the i1Pro 2 and the i1Pro 3, the fixed recording tool, and an answer to the question about step 9.
1. The patch names are now in the turned .txf
@jctay, as promised in post 150184: the turned .txf that ChromIQ writes for i1Profiler (the Preferences > Beta option "Also write an i1Profiler chart that matches the printed ChromIQ sheet") now gives every patch the five tags your own file had: SampleName with the name printed on the sheet (for example 7G), SampleID from 1 to N in the order of the list, and Column, Row and Page with the cell i1Profiler itself gives that patch. Importing a measurement back into ChromIQ works exactly as before.
Your files showed that i1Profiler copies SampleID and SampleName into its measurement, so the names should now appear in the .mxf. We cannot measure a turned sheet here, so we could not check that part in i1Profiler ourselves. If you have a moment, could you measure one sheet made with 4.3.33 and tell us whether i1Profiler shows the names as expected, both in the .mxf and in its CGATS text export? Attaching the two files would help even more.
2. A new Beta option: the instrument's lights
In Preferences > Beta there is a new option,
"X-Rite i1Pro 2 and i1Pro 3: show the instrument's state with its lights (beta)". Please read this first: it is a Beta, it is off by default, and it has
not been tried on a real i1Pro 2 or i1Pro 3 yet. Nobody on the ChromIQ team owns either instrument. Using it is entirely your own choice, and with it off, ChromIQ sends nothing new to the instrument.
The two instruments use different light commands, so each has its own patterns. For each one, how the lights are switched was worked out from ArgyllCMS's own program code and from one recording of what X-Rite's i1Profiler sent to one user's own instrument. ChromIQ sends only light commands seen in that recording, and on the i1Pro 3 also the "off" that ArgyllCMS itself sends whenever it connects. It never writes anything into the instrument's memory.
With an i1Pro 3 (an i1Pro 3 Plus too, which ArgyllCMS handles in exactly the same way), the option shows:
- while it calibrates or measures, the lights behave exactly as without the option. ChromIQ switches its patterns off first, so every reading is taken with the lights as ChromIQ leaves them today (i1Profiler keeps its patterns running);
- after a successful calibration, the pattern i1Profiler shows after its own calibration (we expect a short white blink), then a slowly breathing white light;
- after a reading, two green blinks, then breathing white. Green only means the instrument took a reading. Whether ChromIQ accepts it for your chart is shown on screen as before;
- when the instrument could not take a reading (for example a strip swiped too quickly), two blinks we expect to be red, then breathing white;
- no light when the measurement ends.
With an i1Pro 2 (
@pharmacist, this is the short note I promised in post 150186), the option shows:
- white while the instrument waits for you (for example for you to press its button and read the next strip). It comes on about a second later, so after a quick press you may not see it;
- no light while it calibrates or measures;
- no light when the measurement ends.
Showing white again after every reading is ChromIQ's own idea: the only i1Pro 2 recording was made on a measuring table, where i1Profiler kept the lights dark. If a measurement with an i1Pro 2 ever ends before ChromIQ could switch the lights off (for example after a crash), ChromIQ asks you at the next Start to unplug the instrument and plug it in again before it connects.
In rare cases (ChromIQ is forced to quit, or a light command fails) the lights can stay on until you unplug the instrument. If a light command fails, ChromIQ stops using the lights for the rest of that measurement, says so in the log and carries on measuring as normal.
How to try it
- Install ChromIQ 4.3.33 from the link above.
- Open Preferences > Beta and tick the option. ChromIQ explains what it does and asks you to confirm.
- Make sure Preferences > Measurement > "ChromIQ chart-reading engine" is on (it is, unless you switched it off). The lights are used only while that engine reads strips or single patches by hand.
- Measure as usual. The Measure tab's log says "Instrument lights (beta): on" when they are in use.
What we would like to know
- Do the lights do what is listed above for your instrument? Which colours do you actually see?
- While you calibrate and measure, are they off (i1Pro 2), or do they look the same as with the option off (i1Pro 3)?
- Do readings stay the same? Measure the same chart, or one strip of it, once with the option on and once with it off, and compare the numbers.
- Does the instrument start normally about ten times in a row? Start a measurement, let it calibrate, stop, and start again.
Please also tell us your system (macOS, Windows or Linux), and if anything looked odd, what the lights did and the lines starting with "[Engine] Instrument lights" in the Measure tab's log.
@jctay, two questions just for you, whether or not you try the option:
- Is your instrument an i1Pro 3 or an i1Pro 3 Plus? Your recording does not tell us which, and the option lets both use the same patterns.
- A check you can do even without the option, so with no new risk at all: leave i1Profiler with the instrument's light breathing, quit i1Profiler, then start a measurement in ChromIQ. Does the light go dark when ChromIQ connects? (If your computer needs a different driver for ChromIQ than for i1Profiler, and switching is a bother, please just skip this one.)
If anything goes wrong: switch the option off, unplug the instrument and plug it back in. That returns everything to how ChromIQ always worked. Then please tell us what you saw, here or with "Report a Bug…" at the bottom of Preferences (it opens a form on GitHub).
3. The recording tool, version 1.5.5
@jctay, thank you again for the recording: seven of the nine steps hold exactly what we hoped for. Steps 7 and 9 came out empty because of a mistake in the tool (Enter presses made while it was busy answered the next questions), and version 1.5.5 fixes that. Please note that the fix has not yet been confirmed on a real Windows console, so it is likely fixed, not certain; your run would be the first real check.
If you can spare ten minutes, please repeat only four steps: 4 (dual scan; the tool now asks which setting was on), 6 (the slow swipe: take 3 to 5 seconds for the whole strip, your earlier slow swipes were as quick as the fast ones), 7 (let one scan fail) and 9 (the strip without the ruler).
- Download chromiq-io-probe-windows.exe from https://github.com/itsab1989/chromiq-i1io-probe/releases/tag/v1.5.5 and put it into the same folder as last time, next to the folder instrument-session-... from your first session.
- Start it as before, as administrator, choose 2, and press Enter for the i1Pro 3.
- When it asks "Do you want to repeat only some steps of an earlier session? Type their numbers (for example 7,9 ), or just press Enter for all steps:", type 4,6,7,9 and press Enter.
- Each step then works like this: press Enter in the tool's window to start recording, do the step in i1Profiler, then come back to the tool's window, type e and press Enter to stop. After you stop, the tool says "please wait a few seconds and do not press any key", and then tells you whether the step was recorded.
- At the end it makes one file, SEND-THIS-<date>.zip, with only these four steps and the report: please send just that file.
4. Step 9, and covering the sensor (posts 150188 to 150190)
@jctay, there is no need to cover anything, and I would rather you did not stick tape on the instrument. Step 9 only asks you to take the ruler away and scan the same strip without it, for example by sliding the instrument along a straight edge or freehand. If i1Profiler refuses or shows a message, that is useful too: just note what it said. If i1Profiler does not let you scan without the ruler at all, or you are unsure, type s to skip the step. Please do not force anything.
Your two possible outcomes are both plausible, and I honestly do not know which one happens. Finding that out is exactly what this step is for.
@pharmacist, about doing things too early (post 150187): if that was the recording tool, no harm done, it only listens and sends nothing to the instrument. The rule that avoids it is the one the tool prints before the steps: use i1Profiler for a step only
after you have pressed Enter in the tool to start that step, and read the "Before you press Enter" part of each step first. If some steps went wrong, version 1.5.5 can repeat just those: put it next to the folder of your earlier session, and at the start it asks which steps to repeat.
Thank you both for your patience and your help!
