Hi Javier,
Your question regarding AnyInputFile can be
explained using a demo file that I have created.
Please download the zip file “AnyInputFileDemo.zip”
from the “Files” section. It contain 4 seperate files
once you extract it:
- AnyInputFileDemo.any
- PelvisPos.txt
- PelvisPos2.txt
- PelvisPos3.txt
Open the AnyInputfileDemo.any using AnyBody,
and load the model. Browse to the section where
the explanation of the demo is given (include here):
// --------------Demo Start ----------------------------
// The following three examples show how AnyInputFile
// reads a .txt file. After you load the model, you can
// right click on variables in the model tree, and
// select “dump” to see the value of the variables.
// -----------------------------------------------------
// Example 01: The recommended way - the first column is
// for the Time T and the remaining column are Data.
// “PelvisPos.txt” contain following space seperated data:
// 1 1.1 1.2 1.3
// 2 2.1 2.2 2.3
// 3 3.1 3.2 3.3
// 4 4.1 4.2 4.3
AnyInputFile Data_file = {FileName = “PelvisPos.txt”;};
// You can assign the first column of the txt file to a
// variable using:
AnyVector Time_T = Data_file.T;
// You can assign all the remaining columns (Except first
// column), all at once, using:
AnyMatrix Data_mat = Data_file.Data;
// You can assign individual column (Except the first column)
// data to different variables, using:
AnyVector Data_Col01 = Data_file.Data[0];
AnyVector Data_Col02 = Data_file.Data[1];
AnyVector Data_Col03 = Data_file.Data[2];
// Example 02: txt file contain only one row of data.
// “PelvisPos2.txt” contain following space seperated data:
// 1 1.1 1.2 1.3
AnyInputFile Data_file2 = {FileName = “PelvisPos2.txt”;};
// In this case, the row become the .T and the .Data is empty:
AnyVector Time_T2 = Data_file2.T;
AnyMatrix Data_mat2 = Data_file2.Data;
// Example 03: txt file contain only one column of data.
// “PelvisPos3.txt” contain following space seperated data:
// 1
// 2
// 3
// 4
//The following three statements will fail:
//AnyInputFile Data_file3 = {FileName = “PelvisPos3.txt”;};
//AnyVector Time_T3 = Data_file3.T;
//AnyMatrix Data_mat3 = Data_file3.Data;
// --------------------- End of Demo ------------------
You can go to the model tree, right click on the variable name,
and select “dump”. You will be able to see the value inside the
variable in the message window.
Right now, the way you use AnyInputFile is similar to
Example 02. It works. However, the intent for AnyInputFile
is to read txt file that set up like the one in Example 01.
Hope this demo helps.
Thanks,
Leng-Feng
