Hi Rick and guys,

I'm from Porto Alegre/Brazil and I'm implementing the real time fmri using afni. I was looking for a solution to an error and I found this topic.

So, my error is similar. I developed a script that detect the new patient folder when the exam start and then I start Dimon with the script below:

Dimon -rt \
-infile_prefix $PATIENTDIR/i \
-host $RTFMRI_AFNI_HOST \
-tr $TR_TIME \
-nt $VOLUMES_PER_RUN \
-num_slices $NUMBER_OF_SLICES \
-quit

I'm using a GE 3T Scanner.

I am able to detect the DICOM images from the folder and send to afni in real time only if I use 3 slices. If I set any other slice number Dimon give's me the same error that John describe or this other:


***********************************************
Error: slice missing!
current file : e13384396/s13386501/i13386548.MRDC.48
expected z-offset : -9.2044
actual z-offset : -5.6045
current run : 16
slice number : 2 (of 5)
***********************************************

I get the same error also when I use Dimon in offline mode with a folder without using -dicom_org command, so maybe I think the problem is the order that the images arrived in the folder or something like,...

I made an scan sequency with debug and you can see details below:
