Environment:

Task Designer MCAT and IRTmodel, importing values from a txt file

Attachments:

dim1.txt    

In the MCAT dimensions and IRTmodel a list of values should be written. An easier option would be a possibility to read the values from a txt file.
Right clicking the Dimensions in MCAT and Parameter in IRTmodel should open a file selection dialog where you can select a txt file to import the values.
The txt file should have the values as tab separated.

OR

in IRTmodel there could be a separate import button. Then you could import parameters from a file with the parameter name as the first value (Difficulty, Discriminant, Guess) and tab separated values following the parameter name.
The same logic with the MCAT and the Dimension name as the first vlaue.

What is more practical: to import all values at once (all dimensions in one file) or dimension by dimension (file per dimension)?

Comment by Pekka Räsänen [ 19/May/2009 ]

both go, naturally it is easier to import all values at the same time.
However, if we consider a situation that we add a dimensions later it would be convenient to be able to import by dimension. This is not a problem if overwriting old values works properly. Then you just add new values to the old text file, import all again and that's it.

first implementation of MCAT values import now available in task designer.
in this version:
values should be TAB separated
each column is one dimension
first row can contain dimensions' names (then values will be assigned according to provided names)

import accessible from the context menu of the values table. (right click).

Be aware that there is no connection between values in text file and cards in values table.
It means that values from the first line of the file are imported to the tables first row and so on.
There is no way to sort values table, so order correspondence between file and table is important.

Unfortunately there is no possibility to run Java Applets in OS X using version 1.6, because all browsers are 32bits application and java 1.6 is 64bits only. Running under 1.6 would give us possibility to use table sorting easily eliminating need to pay a lot of attention to ordering values.

Importing of only one dimension does not seem to work properly (at least after sorting the values-table).
One of two things happen:
1) The imported values are placed in the values table in seemingly "random" order.
2) Nothing is imported and no error message is shown.

The importing preview (where 5 first line is shown) looks correct though.
Attached the import-file. More details from Helena P.

this is definitely because of sorting.

This is probably because of the dimension's name - they are case sensitive.

Import to sorted tables now work fine.

+ some logging added. So after import some information about whole process presented.

Resolution lacks IRT importing

Comment by Oleksandr Maslov [ 03/Apr/2013 ]

Now it is possible to import IRT values from Excel-97 files (.xls)
CSV - comma separated values NOT YET IMPLEMENTED

Use toolbar at the left side of the IRTCard table.
