My apologies. What I meant was that I have 18 lower level contrasts. The 2nd level creates 8 stat maps per contrast ?(or am i missing something here). So in the second level analysis I get 18 cope directories that contain 8 stat maps in each, where each stat map corresponds to a single subject across 4 runs . Those are the logs that I sent previously. So, 'report_cope1.log' corresponds to the first contrast of interest in the lower level that in the 2nd level is now combining the 4 runs per subject. If you look at the end of the log the line plot error only occurs for zstat3 and zstat7. I am assuming that zstat3 = subject3 and zstat7 = subject7. Am I doing something wrong at the second level of analysis? I hope this makes sense and can aide in figuring out where I might be going wrong, thanks, blaine Here is a copy of the error : /usr/local/fsl/bin/tsplot . -f filtered_func_data -o tsplot gnuplot> plot 'tsplot/tsplot_zstat3.txt' using 1 title 'data' with lines , 'tsplot/tsplot_zstat3.txt' using 2 title 'cope partial model fit' with lines , 'tsplot/tsplot_zstat3.txt' using 3 title 'full model fit' with lines ^ line 0: Can't plot with an empty y range! convertb: no delegate for this image format (/tmp/magicxQ9KgT). convertb: Missing an image file name. gnuplot> plot 'tsplot/tsplot_zstat3.txt' using 4 title 'reduced data' with lines , 'tsplot/ tsplot_zstat3.txt' using 2 title 'cope partial model fit' with lines ^ line 0: Can't plot with an empty y range! convertb: no delegate for this image format (/tmp/magicKcWSCY). convertb: Missing an image file name. gnuplot> plot 'tsplot/tsplot_zstat7.txt' using 1 title 'data' with lines , 'tsplot/tsplot_zstat7.txt' using 2 title 'cope partial model fit' with lines , 'tsplot/tsplot_zstat7.txt' using 3 title 'full model fit' with lines ^ line 0: Can't plot with an empty y range! convertb: no delegate for this image format (/tmp/magic0ndOAP). convertb: Missing an image file name. gnuplot> plot 'tsplot/tsplot_zstat7.txt' using 4 title 'reduced data' with lines , 'tsplot/ tsplot_zstat7.txt' using 2 title 'cope partial model fit' with lines ^ line 0: Can't plot with an empty y range! convertb: no delegate for this image format (/tmp/magicBxKQCN). convertb: Missing an image file name.
