How can I find "results_6PCW" dataset?

[cristalliao]

Dear Professor, I want to know where I can find this file "results_6PCW" when I try this great STitch3D in Example 2. plot3D_clusters(directory = "./results_6PCW", clusters = clusters, cluster_colors = cluster_colors, um = um, spot_radius = spot_radius, axis_rescale = axis_rescale ) in this part "Run STitch3D on the human heart dataset". Thanks in advance!

Hi Cristal,

You can rename the results folder created by previous steps (which might be "results_human_heart", depending on how you name it) as "results_6PCW".

Hi Geifei,

Thanks for your reply!! After renaming "results_human_heart", the code still does not work:

In the "results_6PCW", it has the following file:

But my R studio, cannot open this file. How to deal with this problem? Thanks in advance!

Hi Cristal,

Could you try getwd() to check your current working directory? It seems that the path you provided cannot be found in R.

Dear Geifei, Thanks a lot! I have already found the problem: I have not stored the clustering_result.csv in the results_human_heart file so I cannot use the plot3D_clusters function. However, there is a new problem, which is: When I run the code, there is no figure generated, like below:

It is a little bit strange. Do you have any suggestions for me? Thanks a lot!

Hi Cristal,

Maybe you need to check whether your R package rgl is able to create a plot normally or not on your side. Here are some suggestions from stackoverflow:

"Output may be on screen using OpenGL, or to various standard 3D file formats including WebGL, PLY, OBJ, STL" ;

"There are two ways in which rgl scenes are normally displayed within R. The older one is in a dedicated window. In Unix-alikes this is an X11 window; it is a native window in Microsoft Windows. On MacOS, the XQuartz system (see http://xquartz.org/) needs to be installed to support this."

"The newer way to display a scene is by using WebGL in a browser window or in the Viewer pane in RStudio. To select this, set options(rgl.printRglwidget = TRUE). Each operation that would change the scene will return a value which triggers a new WebGL display when printed."

Thanks a lot, Gefei! The solution is really helpful. The problem has been solved! Very appreciated! Best regards, Cristal
