I am trying to convert a TDMS file to a .fcs file, which is used in flow cytometry.
I am having trouble implementing this in LabVIEW, my main confusion is due to data types:
I have a 2D array of DOUBLEs, which I get from the TDMS file. According to the specifications, data in a .fcs file can be stored in multiple ways, including as "unsigned binary integers" and doubles (see page 14).
I am writing the HEADER and TEXT segment to a binary file as strings, which should be fine.
But how do I write the 2D array?
Ideally I want the datatype in the file to be DOUBLE, which I can specify by setting the keyword '$DATATYPE' to the value 'D'. Does this mean I can just wire the 2D array into the "data" port of the "Write to binary file"-subvi? Surely not, since the array will also write some array specific delimiters which will corrupt the bit stream of my data to give 'ghost values'.
In the attached vi, I rearrange the 2D array into a 1D array, by appending the rows of the array one after the other. Then I type cast this into a string, which gives me a pure ASCII qword (64 bits) for each number. Is this how it should be done? I've reached the llimit of my interpretation of the documentation (in the link above) and can still not get my files to be recognised by file readers (such as this one).
Kind Regards
