But the problem is not fixed. Now the code is running well but I am getting the concatenated waves without any values. I am attaching a screenshot of it. Could you have a look of this and let me know if you have any ideas? Thanks.

Well, I used a different designation but the problem is not fixed. If I change like that, the code again doesn't run. I am working on it for hours to get the expected concatenated waves with correct length but each time having some issues. Anyways, thanks a lot.
I just looked again at the code and how it works. Forget my earlier answer. I see now how it is supposed to run (I think).
When I run your code, it does the first two iterations (loads the 1st and 2nd dat files) and does the concatenation, on the next iteration it says that it loads the file but no waves have been created in the temporary data folder. This means that the wave references to ProtonEnergyFor_SpecAmpNew etc are NULL, when the concatenate command runs it gives Error: Expected Wave Reference for this reason. I didn't investigate why no waves are loaded on subsequent iterations. I did check if it was something to do with the file, but the code just fails on the next file if I take that particular file out of the directory. Sorry I haven't fixed the problem, but hopefully this brings you closer to a solution.
Switch the debugger on and check out the state of the tempdatafolder when it throws the error. Note that in the history window it says:
path: "Macintosh HD:Users:xxx:Downloads:ONeDatFile:"
Reading from file "s_0340_r_000001_1.dat". Number of Event is: 326

Reading from file "s_0340_r_000003_1.dat". Number of Event is: 270
Loaded file 1: "s_0340_r_000003_1.dat"
Loaded file 2: "s_0340_r_000001_7.dat"
It looks like it doesn't read from s_0340_r_000001_7.dat so my guess is that the bug is with LoadOneNeutronDataFile

Hi,
Thank you very much for your explanation.
I got your point. I tried to modify the code in a different way. For your attention, my target is to read only _1.dat files of series 340. Since Each series has almost 2500 files, so I switched from "Concatenate [/DL /KILL /NP[=dim ] /O] [typeFlags ] {wave1, wave2, wave3,...}, destWave" command to "Concatenate [ /DL /KILL /NP[=dim ] /O] [typeFlags ] waveListStr, destWave" command, since according to Igor manual, the first one is limited to concatenate 100 waves or less, but there is no limit when using waveListStr. Now the code is looping over all files but I am facing another problem, it is not giving the correct length of the concatenated wave. For example, If I concatenate wave1 with N points to wave2 with M points, then I should have a concatenated wave with points (N+M). To check it, I took one file in a different folder (file "s_0340_r_000000_1.dat") and then ran the code. It gave me the correct number of points (274) which is equal to the number of events in that file. Then I add another file (file "s_0340_r_000001_1.dat") to that folder and ran the code again over these two files. Before that, I ran the code for the second file "s_0340_r_000001_1.dat" separately and got the correct number of data points and values in the table which is 326, the number of events in that file. So after running the code over these two files, I must have (274+326)=600 points in my concatenated wave. But instead of that, I am getting 652 points. I guess something wrong is happening when it is overwriting the existing waves, or something else, though not sure. I faced the same problem before also and tried to figure out the issue but couldn't. I hope now you will understand what is going on with the code. Any help will save my so many evening hours working on it.
Again thanks for your help.

I had another look at this. The original code as you have it works, I think the reason it fails is to do with reading from the file. So, I think it works because if you take the dat files ending 1_1 or 3_1 and make copies giving them other names e.g. 2_1, 4_1, and just have those in a directory. The code works. The concatenated waves are the right length and all is good.
So why doesn't it work on the whole folder? If you run LoadOneNeutronDatFile("","") and point it at 1_7, it fails to make the waves (I think), hence the load from directory option is failing.
I don't know enough about the files or the data structure to help further. The error is because of this part:
TimeStampForSpecAmp[k] = Vnam1
k is out of range. This is because:
NumEvent = V_logEOF/8208
which sets the size of the waves, is not a whole integer for this particular file.
Setting it to ceil(V_logEOF/8208) causes the read to crash because it reaches the end of file unexpectedly and throws a different error (ceil takes the integer above).
So, if you can fix this error I think the whole code will run on all files in your directory.

Hi,
Thank you very much for your explanations and suggestions. I have figured out the problem with the code. Now it is running well and giving the concatenated wave with the correct length.
Again thanks for your time.
Concatenate /NP {ProtonTime_SpecAmp}, ProtonTime_SpecAmpNew
Concatenate /NP {ProtonEnergyFor_PreAmp}, ProtonEnergyFor_PreAmpNew
Concatenate /NP {ProtonTime_PreAmp}, ProtonTime_PreAmpNew
The second part is the destwave.

Thank you very much for your reply. I switched the source and destination wave position as you said:
Concatenate /NP {ProtonTime_SpecAmp}, ProtonTime_SpecAmpNew
Concatenate /NP {ProtonEnergyFor_PreAmp}, ProtonEnergyFor_PreAmpNew
Concatenate /NP {ProtonTime_PreAmp}, ProtonTime_PreAmpNew
But the problem is not fixed. Now the code is running well but I am getting the concatenated waves without any values. I am attaching a screenshot of it. Could you have a look of this and let me know if you have any ideas? Thanks.

Concatenate /NP {ProtonTime_SpecAmp}, theConcatenatedWave
Concatenate /NP {ProtonEnergyFor_PreAmp}, theConcatenatedWave
Concatenate /NP {ProtonTime_PreAmp}, theConcatenatedWave
... where theConcatenatedWave is the wave that should contain the concatenated results.
Alternatively, you need to specify a different designation like this ...
Concatenate /NP {ProtonTime_SpecAmp}, ProtonTime_SpecAmpConcatenated
Concatenate /NP {ProtonEnergyFor_PreAmp}, ProtonEnergyFor_PreAmpConcatenated
Concatenate /NP {ProtonTime_PreAmp}, ProtonTime_PreAmpConcatenated

Switch the debugger on and check out the state of the tempdatafolder when it throws the error. Note that in the history window it says:

So why doesn't it work on the whole folder? If you run LoadOneNeutronDatFile("","") and point it at 1_7, it fails to make the waves (I think), hence the load from directory option is failing.
I don't know enough about the files or the data structure to help further. The error is because of this part:
k is out of range. This is because:
which sets the size of the waves, is not a whole integer for this particular file.
Setting it to ceil(V_logEOF/8208) causes the read to crash because it reaches the end of file unexpectedly and throws a different error (ceil takes the integer above).
So, if you can fix this error I think the whole code will run on all files in your directory.

Hi,
Thank you very much for your explanations and suggestions. I have figured out the problem with the code. Now it is running well and giving the concatenated wave with the correct length.
Again thanks for your time.
