How to set the output file name same as input names but with an additional word

I have a few folders each with one .txt file. I load one file at a time using a Matlab GUI:

function load_data_callback(~,~,h)
[FileName, FilePath, FlagUp]=uigetfile({'*.txt'; '*.csv'; '*.xls'; '*.xlsx'; '*.*'}, 'Choose Tab-Delimited Data File');

and make the calculations. Then, the function makes an outputfile called 'NumberOfSpikesPerROI_JCK.csv' by using:

C = ([SeriesLabels;num2cell(SeriesData)]);
writecell(C,'NumberOfSpikesPerROI_JCK.csv')

I want to get the name of the outputfile based on the name of the input file.

For example, if the file name of the first file that I loaded is 'MyFirstFile', then, the output should be 'MyFirstFile_NumberOfSpikesPerROI_JCK.csv' and saved in the same folder (which is currently in Matlab path) as the input file.

Please suggest how to achieve this.

Thank you.

If I understand your code correctly, then you've got

FileName = 'MyFirstFile';

So, you could get your new filename as

newFileName = [FileName, '_NumberOfSpikesPerROI_JCK.csv'] % Use square brackets to concatenate character arrays

newFileName = 'MyFirstFile_NumberOfSpikesPerROI_JCK.csv'

It's just a little bit trickier if your input filename is actually something like

FileName = 'MyFirstFile.csv'

and you are trying to insert the text in the middle. But, the principle is the same. Please clarify, if I have misunderstood your question.

Many thanks! It owrked.

C = ([SeriesLabels;num2cell(SeriesData)]);

writecell(C,[FileName, '_NumberOfSpikesPerROI_JCK.csv'])
