Sorry, I cannot answer your question. But I have another point. You apparently want to show "images of crystals". Likely you mean, you want to display the unit cells of various crystal structures or you want to display parts of crystal structures (without interacting a software). If I look at many papers and many students works, I see many crystal structure images, which tell nothing to the reader. Usually every crystal structure or a series of crystal structure has something specific, WHY it is shown. In my opinion there is no point to show a crystal structure without that the reader can get a message from the image (to show that you are able to draw the unit cell is no message). So think about why you want to show these crystal structures in some way. Every picture in a scientific publication has to tell something to the reader. A collection of balls in a box usually will tell nothing to the reader. Usually such figures are scientifically worthless. Hence, think about whether by this request you intend to produce pictures nobody needs.

Thanks, Andreas for your quick reply. I win a new perspective thanks to your comment. I may mislead you by saying crystal images. If I did, sorry for this mistake.

In gas adsorption and catalatic analysis as in the below article, they show generally images of surface/adsorption systems. As far as I see all papers in this area, I saw images of systems. So I would like to find an easy way to show many pictures in paper.

Ok., in this way it may make some more sense. I think, however, human interference umpon generating the images always will make it better, although it takes some more time.

Thanks Andreas.

Thanks Leonardo it will be quite helpful for me
