I have fixed the error that was causing JoAnna's problem

I have the same problems with the tag section, which I have to comment out. Once I do that, the program works about 80% of the time as opposed to about 30% of the time. I also have issues with the following error:

??? Attempted to access goodstart(1); index out of bounds because numel(goodstart)=0.

Error in ==> abfload at 277
 BigString=BigString(goodstart(1):end)';

Forrest, I ran into a problem with abf files containing tags. When I try to load them I get the following error:

??? The following error occurred converting from struct to double:
Error using ==> double
Conversion to double from struct is not possible.

Error in ==> abfload at 327
        Tagsec(i)=ReadSection(fid,TagSection.uBlockIndex*BLOCKSIZE+TagSection.uBytes*(i-1),TagInfo);

The problem seems to be in the line just before (line 325):

Tagsec=[];

This creates an empty double array, but output of the following loop is a struct. Simply commenting line 325 solved the problem for me.

Thanks again for an otherwise great function.

Apologies.. The file I was trying to load seem to be corrupt and couldn't be loaded by pClamp 10, either. So please ignore the previous post. The correct files can be read by abf2load. Thanks!

I am getting this error with some ABF2 files from pClamp10:

There are only about 7000 Strings, so this is way out of bounds. I also tried the python version of abf2load that is part of Neo, but that chokes on these files, too. I can send a copy of the file if you can take a look at it.

Thanks for the otherwise very useful utility!

(molecular devices developer page link is broken now. Is there a way to get to that code?)

I can read gap free abf files only if statements 326-329 are comments. This problem was seen before and I thought it was fixed. I have MatLab R2009 student edition runing on MS Vista.
