I hade to create a movie in Matlab as temporal sequence of images of a matrix I(512*512*30) double , because I have 30 images(512*512). I tried to apply this code, but it doesn't work, and I don't know how to solve the problem
map=colormap(gray); [X,map]=gray2ind(I); mov=immovie(X,map) movie(X,n_rip,fps)
this is the error: %Error using immovie>parse_inputs (line 84) %Indexed image has to be an M-by-N-by-1-by-K array.

See my two attached demos on how to make a movie/video.

The second line of your code starting with an equal sign won't execute. You say that you have a 3D image I (512,512,n_image) which is probably a color image. So in I(:,:,1,frame) the third dimension is the red channel. But what is frame? I is just a color image - it is not a video so it has no frame. Plus that assignment just won't work
[Im(:,:,:,frame),map] = I(:,:,1,frame);
because I is an array, not a function so you can't take something from teh I image/video and assign it to two things.
Tell me what are you trying to make a video of? What is changing as the frames go on?

I selected from a folder 30 rmi images dicom and I put all this 30 images in I, because I need to order images according to istance number, so now I have this matrix 512*512*30 and I should create the movie with all 30 images.I thought to create a 4-D matrix whit the command
A=cut(4,X(:,:,1),X(:,:,2),X(:,:,3),..,X(:,:,30))
and then
mov = immovie(A,map);
implay(mov,n_rip,fps)
but doesn't work..
