There's something over a hundred BioEra elements in Design and only computerese descriptions of them. Any chance anyone could upload a list of the elements' icons with their corresponding computerese descriptions?

Jarek, any chance of uploading a link to a poster showing all the current icons of BioEra design elements?
It would be very helpful if they could be shown together with the label they're given in Design's drop-down list.
And, preferably, segregated taxonomically into connectors, inputs, etc., etc.

Only some elements have their own specialized icons. Those which are used the most often.

Most elements (>90%) use a default icon. So such a list would not be very helpful.

Dear Jarek,
I am not an electronic engineer. I am a retired doctor with an intense interest in how the brain works, as revealed by the EEG.
To me, BioEra Design's elements are like trees in a jungle with meaningless Latin names and, in that I cannot see the icons until I select them, it's also like wandering in the jungle in the dark.
I simply want a hands-on opportunity with someone who uses BioEra so I can see how to use it. I know of no-one in Vienna nor even Europe who uses it although I know it is widely used. There seems to be no way to connect up with people sharing an interest in BioEra.
Eventually I wrote to a poster who, several years ago, left a contact. He kindly replied: "Thanks for reaching out John, unfortunately I never could find enough help/information to get into using BioEra, so . . ." which says it all.
There is a huge market for BioEra but there are no first steps. BioEra is seriously neglecting its opportunities and will lose market share and dwindle unless the threshold of entry to its use is much reduced.
You, Jarek, are a noble exception to this neglect and, indeed, are as helpful (and certainly knowledgeable) as the rest of the company appears neglectful. But your help and expertise is clearly at a higher level: for those familiar with the basics of computerese and electronic circuits. The company doesn't deserve you because the huge development potential more users offer is being stifled by inaccessibility at the start.
If you can put me in touch with any others currently using BioEra I would be much obliged because extended discussion over problems may be possible - in a way that is not possible within the confines of the forum. There appears to be no interest whatsoever from BioEra in setting up an elementary workshop which, I'm pretty sure, would be heavily over-subscribed.

BioEra is a development system. To create complex designs it does require a technical background and some experience with programming at least on a basic level. It is not a product to use for biofeedback directly after installation. The examples are there only to help as a demonstration.

Yes, it is difficult to start with. That is because of hundreds and thousands of options which were requested by customers during their development. It started small and has grown like that.

We can have either simplicity or flexibility. BioEra is the latter. A workshop is not enough to cover even small part of that. Many customers work on their designs for months. Advanced software engineering is almost a never ending process, there is always something which can be improved.

The best way to learn is to start with small designs (2 or 3 elements) and experiment and learn from that. Analyze snippets posted on forum. Analyze example designs. And if something is unclear or looks buggy, post a specific (narrowed) question here.

I know this is probably not the answer you were looking for.

Yes, Jarek, I agree with all that you say and certainly BioEra's flexibility is a big plus.
But simply choosing elements when you've no (or very little) idea of what they do is like blundering in the dark. Beginners can't even distinguish compatible elements because there's no classification available on which are compatible elements.
I know any workshop could only scratch the surface but it could illustrate the basic mechanics. I think you and BioEra might be surprised if a competent user, say somewhere in Europe (preferably Vienna!), were to advertize even a one-day workshop/presentation - or even a single lecture somewhere.
At the very least the cost to BioEra would be modest and covered by the fee. At best it would bring in a huge number of new users who would likely be impressed by BioEra's undoubted versatility.
If you do know anyone who might be interested in contact, please feel free to pass on my email to them: johnmarks9@hotmail.com

If you want to create your designs by yourself (as oppose to hire someone), then my only advice at this moment is to start slowly and small.

Start from an empty design, add SimulationSource and Oscilloscope, connect them. Change properties, see how they affect the behavior. Then add a Filter element between, and so on.

Another approach is to load a snippet (search for .bpd files with links on forum) and experiment with that.

For more details about each element you try, see the manual: http://proatech.com/be/manual.html

BioEra example are more complicated, so I wouldn't start with that, unless you only want to execute and play with the user interface.

If elements are not compatible, you will not be able to connect them and see an error.

While it does take time to master BioEra I have been happy I spent the time to learn as much as I can. I am not a programmer, nor engineer. Just a NFB practitioner. The manual is helpful but itisdifficult to go through. I learned by getting a few snippets, and tearing apart some of the examples and the nested designs inside them. Jarek's responses on the forum are also very helpful.

It is but if you decide what you want to do and sketch that out for yourself. Then looking through the manual, search it if you like, to fined elements that can do what you want. One of the difficulties is that BioEra elements are geared toward a single function. So to create elements such as a fully functional threshold means combining several different elements.

I would be glad to talk to you about getting started.

Thanks for your kind offer, GM.
And to Jarek for his last very helpful, if general, post.
First up, would you be able to send me a sheet of the hundred or so icons so I can see what they look like? Even better would be if the chart of icons could group elements by function and ones that are compatible together.
Another problem I have is the design window freezing - which Jarek doesn't think is a Windows/BioEra interface problem, i.e. it's not a bug. Maybe I need to reload BioEra? Or are you familiar with this irritation and know a way around it?
Thanks in anticipation.

Here is the folder in the BioEra folder that has the Icon images for the most commonly used icons.

BioEraPro\images\designer

If you are exploring how BIoEra works, compatibility is clear when elements are in the designer scree. There color of the nodes should match. Green output to green input, blue output to blue input. There are cases when this differs but for the most part it holds true.

When I was first learning BioEra i found that placing elements in the design based on function was easiest. I would visualize what the design shoes do from signal input to signal output, the place the elements based on that.

I think of it as

1 Input
2 Processing
3 Feedback

Input would be devices from the device set or single device elements.

Processing includes bandpass filters, mathematical operations

Feedback is displays and sounds.
