Hi
I've been attempting to run sfs on single nac images. I had been following the exact steps mentioned in the documentation, however they are not sufficient. I've been stuck on spiceinit for several days. Everytime I apply a fix, some new issue is encountered. The root cause is that I have to run it on an offline linux based server. So each time I have to download and load the files manually.

currently, the issue that I'm encountering is "the ck rotation from frame -85600 can not be found due to no pointing available at requested time or a problem with the frame". I found a similar thread on github issues, and downloaded all the required files mentioned there through the download isis data command on google colab, and transferred them on the server. I'm not sure which file is missing right now.

your earliest response would be highly appreciated.
Thank you for your time!

Try to see if you can run spiceinit with web = true. 

An offline approach is not great for this kind of work.

As to what kernels you will need, if you want to download them one by one, there is a about a dozen of them for each cub, and they are enumerated in the plain text part of the cub file.
