Why my matlab code cant load the directory that i wanted it to load instead read the weird file and say no directory

pdir='/Users/Phong/Desktop/RK4/'

load this 

nameS=strcat(pdir,'InitCond30/','InitCond30_',int2str(run))

                  load(nameS);

it supposes to read /Users/Phong/Desktop/RK4/InitCond30/InitCond30_run

But it did not run that directory instead read the weird file and double letter like this

Error using load
Unable to read file
//UUsseerrss//PPhhoonngg//DDeesskkttoopp//RRKK44//IInniittCCoonndd3300//IInniittCCoonndd3300_ run:
No such file or directory.

Anybody has any idea why It reads and double the letter like that and how to fix it. Thanks

Did you check what string nameS actually contains?

It runs with other run, but somehow it did not run the last run

ex: run= 1: 10

then all runs from 1 to 9 is worked, except 10.

I think you need to post more of your code for us to be able to understand this. A shot in the dark:

clear nameS at the beginning of each loop.

[Phong Pham]

I generated the file in the folder InitCond30 with all run from 1 to 10

InitCond30 folder is located in /Users/Phong/Desktop/RK4/

It will create InitCond30_1, ....10

Now I want to load these files

pdir='/Users/Phong/Desktop/RK4/'
for run=1:10
  if ic== 1
    nameS=strcat(pdir,'InitCond30/','InitCond30_',int2str(run))
    load(nameS);
  end
end

The funny thing is they ran all from 1 to 9 and it did not run the last run 10.

[EDITED, Jan, code formatted - please do this by yourself, thanks!]

Did you check what string nameS actually contains when run=10?

Loading directly to the workspace cab have unexpected results: What happens, if one of your MAT files contain a variable pdir? The result of the next iteration might be unexpected.

Therefore it is recommended to store the output of LOAD in a variable:

Data = load(nameS)

or Data{run} or whatever. Maybe this would solve your problem, but even if not, it is a good method to improve the quality of programs.
