Bash script to ignore save errors when processing multiple images from command line with Cell Profiler

ignore_CP_save_erros.sh

#!/bin/bash
n=1 #Image Set number to start processing batch
final_image=826 #Last Image Set number in your batch
cellprofiler -p ML/Batch_data.h5 -c -r -f $n -l $final_image |& tee log.txt #Here the output from terminal is save to log.txt.

while [ $? -ne 1 ]; do
  #Parse log.txt file, extracting the image set # at which the error occurs
  no_save_error_image=$(sed -n '/^.*ValueError:/{n;p}' log.txt | sed -n -e 's/^.Image # //p' | sed -n -e 's/, module SaveImages.$//p')

  #Restart CellProfiler at the next image set
