• Frequently Asked Questions (FAQ)
  • 1. What is the PhysIO Toolbox?
  • 2. How does PhysIO differ from other toolboxes for physiological noise correction for fMRI using peripheral recordings?
  • 3. How do I cite PhysIO?
  • 4. Where do I find more documentation for PhysIO?
  • 5. I am using FSL, AFNI, BrainVoyager, etc., for my fMRI analyses. Do I need SPM for PhysIO to work?
  • 6. I am using device X for physiological recordings. Does PhysIO support the physiological logfile format Y?
  • 7. I am running the toolbox for a lot of subjects / on a remote server without graphics. Can I somehow reproduce the output figures relevant to assess the data quality?
  • 8. How do I interpret the various output plots of the toolbox?
  • 9. I want to access subject’s physiological measures, e.g. heart rate or respiratory volume (per time), before they enter the regressors. Where can I do that?
  • 10. What is the order of the regressor columns in the multiple regressors file?
  • 11. How do I know whether the physiological noise correction worked?
  • 12. Philips: I would like to use the gradient log for timing synchronization, but how do I set the thresholds?
  • 13. How do I know which logfile type (‘vendor’) I have to choose?
  • 14. What does Parameter XY mean and what is its best setting?
  • 15. I don’t have Matlab, can I still use the PhysIO Toolbox?
  • 16. PhysIO fails already when running your provided example data, e.g., with “Out of Memory” errors. What happened?
  • 17. Which models do I have to include in my physiological regressor matrix? And which number of regressors (model order / delays) per model?
  • 18. I cannot find the answer to my question in the FAQ. Whom do I ask for help?
