Hello,

Typically, the mean image is created during the preprocessing steps and "mean" is appended in the beginning of the file name (SPM style), not to end of the file name, and certainly never in the middle! So in that sense, the "meanesting_state.nii" is a weird thing to see. My first instinct was to assume that a particular subject had "r" of "resting_state.nii" missing and hence the whole problem, but since you say that it has been running successfully sometimes, it gives me pause.

Another weird thing that I notice is that it is referring to the image dn_p004...nii. The reason this is weird is because you have reached the normalization stage. Before that, other files would have been created (during say slice timing correction, segmentation, etc.).

What is/are the preprocessing steps you are running? Are you running the Conn default pipeline or something different? Also, you mention that you are trying to import raw functional data from a few subjects. Can you clarify how you are importing these data into Conn? Perhaps you are running a script here?

Finally, it might also be a good idea to quickly check that there are no errors in file names (in case you are using a script to load files). What is the name of your nii file to start with? 

Best
