TDMS read "loses" data when used in multiple instances

[JohnnyF]

My original code used a for loop. I tried creating a simplified for loop without the post-processing at the start of my troubleshooting and then went to the individual reads as in the VI in the image above. I will attach the original executable for perspective.

I need to open and process three to five files. The issue I am seeing only occurs in the second and third read.

I will try to attach a data file but I suspect it will not work. The data files causing the issues are approximately 25 mb in size. I can run the same sequence on files I have generated that are around 1.8 mb without issue, but unfortunately I do not see a way I might be able to cut down the size of the data files, as I need to observe transient effects in between loading applications.

You can have a faster way to determine the number of for-loops to run:

 

Maybe your problem lies in the missing initialization of the shift register in the upper minor for loop:

Thanks for the advice-always nice to find a way to increase speed.

Regarding the uninitialized for loop you pointed to, that does not seem to affect the results as I see the same erroneous data when I run my simplified code like this one:
