Time-scale for accurate measurements in chambers

By Saket Navlakha

The last of my current barrage of questions :) We are doing growth experiments in chambers. I assume the most accurate measurements will come if we measure The One (Phi2, PhiNPQ, PhiNO) while the plant is in the chamber. But let's say we remove the plant from the chamber, and then measure these values. How long can we wait before we start to get highly different measuremen... read more

Leaf thickness availability?

Hi, does the latest MultiSpeQ device include the leaf thickness functionality? I was testing an old version, and I believe this feature was missing (even though there is a protocol for this). Thanks.

new question:

By Greg Austic

POSTED BY STEPHANIE --> Hi Greg, My name is Stephanie and I just started learning how to use PhotosynQ to collect and analyze data. I made a trial project named Tomato Trials and am currently taking a bunch of measurements just to learn how to use the device and figure out the uncertainty of the measurements. Is there a way to hide select data without having to filter... read more

Difference between protocols - The Ones

By Beatrice Landoni

The One v3.0 (Phi2, NPQt, using Multi-Phase Flash) The One Protocol (Phi2, PSI, NPQ) II What is the exact difference between these two protocols? Should I use version 3 because it is just the last version of "The One" protocol or are there differences that make them suitable for different occasions? Maybe it is a very basic question, but I want to make sure I have grasped... read more

Missing Data

By Veronica Greve

I took measurements yesterday (11/24) for the isolated endophytes project. All of the questions, like plant number, pot id, etc..., are not appearing. Nothing should have been different -no project changes were made between 11/17 and 11/24. The data and measurements are there, just without any identifying information. http://photosynq.org/projects/isolated-endophytes-in-m... read more

We configure a new proyect to perform measurements with the one protocol + SPAD III, and we made some test measurements but spad III does not show data. What could be the problem?

Editing the Active Carbon in Soils Protocols

By Dan TerAvest

I'm trying to design the new macro for a project that would allow field measurement with a somewhat more fine-tuned lab protocol (to keep separate from a photosynq 'protocol'). It seems from talking to Veronica that changes to prompts might need to be partially or entirely changed within the protocol level rather than the macro, and then the macro calls the data filled in ... read more

Column Heading Overwriting Question?

By Veronica Greve

For a cassava project, I had a question titled Rep with answers 1-4. When I look at the data, I can filter it by Rep and see the correct labels, but there is not a separate column for the Rep question. All of the other data is in the right place. Is this a problem with the question being named the same as one of the column headings? I haven't had this problem before labelin... read more

Hi Greg, After the last update (version 3.1) we are observing a error message in either quick or projects measurements that says: "Unfortunately, PHOTOSYNQ has stopped".

Thanks in advance for your help, ... read more
