Text files for different types of data

Hello all,

I have a doubt about how I should work with text files in the following case.

I choose a picture, a pattern from a list and I click a set of points. I can repeat the operation every time I want, and I write the data after every time. This makes me have a text file which looks like this:

Ruta de la imagen: %Path

C:\Users\Nerea Zubiaurre Altu\Documents\MATLAB\Vascular\vascular3.jpg

Patrón: %Pattern

No vena

Puntos: %Points

2.746032e+002 2.207196e+002

2.656581e+002 1.772720e+002

2.835483e+002 2.462770e+002

2.861040e+002 2.437213e+002

Ruta de la imagen: %Path

C:\Users\Nerea Zubiaurre Altu\Documents\MATLAB\Vascular\vascular7.jpg

Patrón: %Pattern

Vasos ramificados

Puntos: %Points

6.707429e+002 2.258311e+002

6.822438e+002 2.271090e+002

6.873552e+002 2.271090e+002

6.924667e+002 1.708827e+002

6.924667e+002 1.708827e+002

Afterwards, I want to import this data again to matlab to work with it but I am finding it complicated as there are different types of data. So I ahve tried as well saving them in different text files. That way, I can obtain the types properly but I cannot define the number of points (as I get a Mx2 matrix of doubles) and the number of point is variable from time to time....

Any idea or help?

I hope I made myself clear!
