I really like to use dot separator as an universal separator, also in filenames, now trying to find a way to use it with animate package. Code where the filename gait.ataxia fails but also surrounding it with curly brackets fails: {gait.ataxia}

        % TODO fails here

Output: ! Package animate Error: None of the files

Output with surrounding extra curly brackets: ! Argument of \end has an extra }.

Testing AlexG's proposal

Adding \usepackage{grffile}, clear the errors but the animation itself is full-stop where action links do not respond. Without filename.dot structure, the animation works normally.

Output: animation in full-stop + animation link actions do not respond

    Hm. Works out for me. I will put together an example on ShareLaTeX.

    Well, on ShareLaTeX it works even without grffile.

    I seem to use a different mirror site for TL updates. I test without grffile tomorrow.

    No change, grffile still needed.

    No output file. It does not compile. ! LaTeX Error: Unknown graphics extension: .file00000.png.
