MRI analysis tools
Manual to perform B0 unwarping with FSL on data from Philips scanner
Pupil analysis toolbox for Brain Vision
This toolbox allows you to read Tobii eye tracking data into Brain Vision Analyzer. Make sure that your Regional and Language settings have been set to English (United States) before acquiring and analyzing data. Otherwise the macros will not load your data successfully.
Matching luminance avg+stdev of a picture or all pictures in a folder
These Linux bourne shell scripts (single picture, all picture in folder) will automatically match the luminance average and standard deviation of all gray-scaled pictures in a given directory to a reference picture by changing their brightness and contrast. The scripts use ImageMagick commands, so the free toolbox ImageMagick should be installed first.
Questionnaire in E-Prime 2
This E-Prime file allows you to present one or more sheets of 10 questionnaire items (with a max of 9 options) in E-Prime. The answers given by the subject are automatically stored into the edat file (see attributes ChosenOption and ChosenOptDes). The questionnaire is programmed in a somewhat quick and dirty (obscure) way, needing many lists, procs and scripts… However, the underlying principle is very straightforward: Whenever the procedure RunOneSheetOf10Items is executed, it presents the content of 11 consecutive rows (1 header and 10 questions + items) stored in the AllQuestionnaires List.
It is very simple to modify this script to suit your own needs! Call the procedure RunOneSheetOf10Items at the proper location in a particular list in your experiment and repeat this for the number of sheets you would like to present. In order to change the text for the header and items + options, you only have to change the content of the AllQuestionnaires List (note that row numbers 1-11, 12- 22, 23-33 etc. will be presented in separate sheets). ItemIDs fields that are left empty will not be used, neither are option fields that are left empty. Optionally, you can set the PreSelection field, when a particular item number should be preselected in advance.
MNI152_T1_2mm standard brain with skull and uniform black background
This edited MNI standard brain allows you to make the background color of screenshots made in fslview transparant in MS Office while at the same time not affecting other “black” regions inside the head/brain.
Adding error bars to a chart in Excel using a macro
|If you want to avoid adding error bars to a chart in Microsoft Excel manually one-by-one, consider to use a macro in Visual Basic for Applications. Feel free to use/edit the example provided here: Excel_add_errorbars_to_chart_using_macro
