I’d wanted an easy way to make an animated Gif. Initially searching gave me all web apps which had unfortunate size restrictions and produced low quality gifs.
Luckily, I found a command line tool called Gifsicle.
You can install it with Homebrew.
brew install gifsicle
I had a folder named cas9_png full of images I’d wanted to turn into a gif. They were .png files so I converted them into .gif files using sips. I then combined all the .gif files into a single animated gif using Gifsicle.
cd cas9_png mkdir cas9_gif sips -s format gif *.png --out cas9_gif cd cas9_gif gifsicle --loop --colors 256 *.gif>cas9.gif
Viola! My gif of a Cas9 protein molecule!
