Comments about the workshop

Pace:

• Very good pace: 7

• A bit rushed at some moments: 2
• Too slow at some moments: 3
• Too much time spent on sensors overview / pre-processing: 2
• Questions from the audience should be taken at the end of each phase: 1

Structure:

• Two-day workshop: 2
• One-week workshop (SPM-like): 1
• Two groups for people with different backgrounds: 1
• Follow-up training with priority to today's participants: 1
• Some time for having people use their own data: 2

User presentations:

• Should be more related to the software and methods, how the analysis were performed: 9

• Waiting too long before starting the practice / presentations should be after the practice: 3

• Less presentations: 2
• Presentations are not necessary in a one-day workshop: 1

Technical issues:

• Graphic cards problems: 2
• Computer was too slow: 1

Missing topics and requests

• More statistics / group analysis: 7

• More methodological details, good practice & cooking recipes: 5

• More connectivity: 3

• Scripting: 2
• Preparation of the MRI: 2
• EEG analysis: 2
• Medical applications: 1
• Baby/infant MEG analysis: 1
• More time-frequency: 1
• Forward and inverse modeling: 1
• Other source reconstruction methods: 1
• More scientific background for less experienced MEG users: 1
• How to handle multiple runs: 1
• Creating structure of data to plug in already processed data: 1

Missing tools in Brainstorm

• ANOVA, clustering analysis: 1
• Yokogawa MEG160 support: 1

Planning to use Brainstorm specifically for:

• Connectivity: 10

• Source reconstruction: 5

• Pre-processing: 4

• EEG: 7
• MEG: 5
• Baby/infant: 3
• Epilepsy: 2
• Time-frequency: 2
• Comparison with Matti's MNE: 1

Comments about the survey questions

• First question: 1(best) and 5(worst):

  • Very counter-intuitive given the amount of people who wrote 5 saying then "Amazing workshop!" => Converting to ones

  • 4 values with no comments are difficult to interpret
• Question about the tutorials:
  • Not easy to understand given the number off-subject responses
  • Maybe we should add a question about the quality of the online tutorials, not the comparison with the class
• Question about the future use of Brainstorm:
  • Too many people didn't write anything, it was probably too open
  • Maybe we should offer a multiple choice. What are you planning to use Brainstorm for: EEG, MEG, pre-processing, source analysis, time-frequency, connectivity, clinical, research, simulation...
