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

After the last update, we can't use PhotsynQ

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".

Issues with measuring wavelengths

By Anne Stanton

I went to the field yesterday and was unable to access the new project that I had submitted the day before, so I put the measurements into another project. I've downloaded the data and it seems to be in the right place, only it doesn't seem to include data for Green, Red and Blue wavelengths as had been included in all the other data. Can you advise me?

Statistical information

By Anne Stanton

I've been working with the statistics calculation page which is really great and very intuitive for me to use. I'm wondering whether there's any way to print out some of the information and graphs that are produced by the analyses? Thanks

chrome crash

By Craig White

Something odd to think about. When I attempt to open the Photosynq website with my android phone using google chrome it always crashes. Multiple attempts over 30 day period. No other site does that. That is just the website not the submit test part.

My unit may have a major issue

By Craig White

I think my unit has a major problem. The symptoms are the batteries won't charge, when hooked up to power through the usb the unit will power on but when an attemt to take a measurement the software gets to the point of "initializing please wait", that is as far as it goes. I wonder if I need new batteries but I have only taken 20 or so measurements since I got the unit may... read more

Exported csv fields shifted

By Greg Austic

QUESTION from Colleen: I did notice that the column titles are in the incorrect order in the spreadsheet both on the photosynq website and when you download the data in a spreadsheet. I attached an Excel spreadsheet where the first row lists the column labels in the order in which they are downloaded from the site. The second row lists the column labels in the order that ac... read more

Data Movement

By Ashley Wieczorek

Can I add new groups and move data points around? For example I had a few data point get put into the wrong group when I measured them and would like to put them in the proper grouping. Also I forgot to make a special group for some of the plants I measured and would like to put them in a new group to make looking at data easier.

My Multispeq doesn't turn off after 2 minutes anymore

By Anne Stanton

Hi, I have been using my multispeq quite a bit and I think it may be beginning to revolt. Last week when I was taking measurements in the field it no longer shut itself off after 2 minutes. It did the same thing today and took measurements normally until it completely quit. I thought maybe it needed new batteries but when I opened the battery compartment the batteries we... read more

What kinds of info indicate a datapoint is invalid?

By Anne Stanton

Hi, I'm trying to sort through my dataset and determine which datapoints are useful and which ones ought to be discarded (probably due to operator error). At this point I question the NPQt values that show up as negative. Can these be disregarded and the rest of that datapoint kept or is the whole measurement suspect? Is there tutorial for how to sift through the data an... read more

What do NPQT, FoPrime and FmPrime stand for?

I'm now at the point where I want to download some of the data I've collected and I can find definitions of some of the parameters that I've measured (phi2, LEF, SPAD, PAR), but I'm wondering what these others are? Thanks

firmware update instructions

By Craig White

I'm getting lost. I have downloaded Teensy and Arduino. My computer does recognize the MultispeQ now and it does have a firmare upgrade. I download the .hex file, reboot and that is it. I get a rebootx. I have not been able to find the Teensy Loader to finish the steps in the instructions. Any help appreciated.
