proposals for fmriflows logo

@ofgulban - I might have gone a bit overboard with the cyclic animation. I created 256 images (each with 8192 parcels). It took 2h to create all figures per colormap, but I'm happy to create other ones if you're interested.

I found a good homepage that has some nice cyclic colormap examples, that you might also appreciate: https://nicoguaro.github.io/posts/cyclic_colormaps/

I tried to create some small gifs of 6 different colormaps. You can find all the figures in higher resolution, as well as the gifs here:

Spectral (with correction for tritanomaly)

Twilight (with correction for tritanomaly)

Colorwheel (with correction for tritanomaly)

HSV (with correction for tritanomaly)

erdc_icefire (with correction for tritanomaly)

nic_edge (with correction for tritanomaly)

Hi Michael, I will have a look into this with pleasure :)

[miykael]

By the way, @ofgulban don't forget to add yourself and your affiliation to the .zenodo.json file. I'm not sure if the final publication will be via zenodo, but it's clear that you will be on the paper!

[miykael]

Closing this issue as @ofgulban created a great logo!

[miykael]

Cool, thanks! But no stress :-)

[miykael]

@PeerHerholz - what do you think about @ofgulban's logo proposals on the gitter channel?

[PeerHerholz]

Oh boy, that's hard decision.

1. @ofgulban should make a business out of his amazing skills!
2. I would say something from option 4 to 6, but would adapt the top left corner of the "fMRI" part as it extends beyond the brain in the background. I actually do like blurry transitions (based on my Bob Ross experience), but if option 4 is out, 5 or 6 are also fine.

[ofgulban]

Thanks, I have created a version 7, pushing the top left corner of fMRI part inside the brain following @PeerHerholz . It is the same document, have a look again. Once decided, i will push the svg version of the graphic so it can easily be edited in the future anyway.

[miykael]

Thanks @ofgulban - Having the fMRI inside the brain is top. I would go for this! And yes @PeerHerholz, Faruk should make a business out of this 👍

[miykael]

Now, I have some highres PNGs that should work much better with vectorization. And I also played around with the number of parcels and the direction of the color gradient.

Annoyingly complicated to explain why, but the gradients shown in the figures are called:

 +x     +y     +z
 -x     -y     -z
+xy    +xz    +yz
-xy    -xz    -yz

128 parcels

256 parcels

512 parcels

1024 parcels

2048 parcels

[miykael]

Sorry for image overload. But which color gradient and number of parcels do you prefer?

I prefer +z (1,3), +xz (3,2) and +yz (3,3) as gradient direction.
And 2048 or 256 parcels.

[ofgulban]

I like 2048 parcels +xz & -xz because the central sulcus looks cool.

@miykael can you produce a version of one of these images with color cycling?. I can create an ever-flowing animation with fmri flows overlay if you provide the frames. This would be an extra fun thing to try.

[PeerHerholz]

Do you mean something like this: https://twitter.com/miyka_el/status/1028027334245285889 ?

[ofgulban]

Yes. It would look smoother if the colormap is extended and mirrored though. So the red does not neighbour blue while cycling.

[miykael]

uiuiui... @ofgulban - that sounds super cool!
How do I create such an image with color cycling? Currently, I just create a PNG file with nilearn's plotting function. PNG is about 1.5MB for about 8000x6000 and 40MB for SVG version.

[miykael]

For this to create a GIF, do you need one image and just have some information about the color cycle or do you nonetheless need multiple images, with each being at a different color phase?

[miykael]

Here the highres PNG files for...

2048 Parcels

4096 Parcels

8192 Parcels

[ofgulban]

@miykael I think many images with different colormap phase would be enough for creating the animation.

I have created a new version of the logo with 8192 parcels png. Have a look at it. For me it looks a bit too dark on the bottom part, so maybe this was not the best gradient direction.

[miykael]

@ofgulban how many different phases do you want for the animation? It takes some time to create them, but I'm happy to provide them.

I love the new 8192 parcels logo and I agree that it's a bit too dark at the bottom. I tried to find some new directions. What do you and @PeerHerholz think?

Alternative 1

Alternative 2

Alternative 3

[ofgulban]

@miykael thanks michael I will update the latest version with these 3 alternatives.

For the gif, I would say 12 frames per second over 2 seconds could be a starting point. So 24 phases.
If needed we can make the animation slower and fill in the gaps later. I think for the initial animation we can make do with lower resolution images with less parcels.

[ofgulban]

I like 11 the most now.

[miykael]

Thanks, @ofgulban! I also like version 11 the most. @PeerHerholz, what do you think?

[ofgulban]

I am mesmerized. Thanks for the cyclic colormap link, I didn't know that site very cool. I like twilight, icefire and spectral. Spectral could be cooler to have it cyclic:
instead of R----->B, having it R------>BB<------R it should be possible to do this mirroring with cmaps but I dont have time for it now.

I will create animated logo versions and lets see which one look the best together with the text. This might take some time due to my current schedule.

[ofgulban]

@miykael @PeerHerholz have a look at the animation here.

You can try other animations as the underlay, a have tried a few but this one looked the best so far.

[miykael]

WOW 😍 that looks so cool @ofgulban - thank you for making this. I love anim_02_overlaid.gif. I prefer it over anim_01 because it has much more an "updating" effect, where anim_01 has a cyclic pulsing effect :-)

We will definitely use your gifs once we announce the software on twitter! I'm so excited! :-)

[ofgulban]

The bash script for creating the gif is there, you can try different inputs or for instance remove the optimization. Will look sharper but increase the files size.

I have created a separate overlay text in the .svg file. In case if you want to change colors of it etc. you can do it from there and export it as png.

[PeerHerholz]

@miykael, @ofgulban, this is nothing but awesome.
+1 for anim_02_overlaid.gif

At this point a set of different versions should be submitted to the OHBM art competition!

[miykael]

I'm all for OHBM art submission, but how? And which design? With the logo or without?

[ofgulban]

When is the deadline for this?
