Hello folks,

I have 2 types of data in Data folder. I would like to loop through it. How can I make it work please.

```julia

Data = glob("Data_Weight")

Load_Data("Data_Weight/Model_Synthetic_Star_/*", 
                         "Data_Weight/Weight_Synthetic_Star_/*")

end

```

Your question is very unspecific, so as a first step I refer you to  
[https://docs.julialang.org/en/v1/base/file](https://docs.julialang.org/en/v1/base/file)  
where you e.g. find:  
`readdir()`  
or  
`walkdir(".")`

If you want to use Glob.jl then something like this can be useful

```julia
for name in glob("Model_Synthetic_Star_/*", "Data_Weight")
# load first portion of data using `name` of the file
end

for name in glob("Weight_Synthetic_Star_/*", "Data_Weight")
# load second portion of data
end

```

First argument of `glob` defines search paths and second argument defines root (and all paths are calculated relative to this root).

Thank you for your suggestion.  
I developed this code. I would like to enter inside of it, but I have an error.

```julia
using Glob
using EasyFITS

for names in glob("model/*")
    for name in glob("weight/*")

        DATA = read(FitsArray, names)
        WEIGHT = read(FitsArray, name)
        DATA = names[:,:,:]
        WEIGHT= name[:,:,:]

    end
end

```

Error:  
ERROR: LoadError: MethodError: no method matching getindex(::String, ::Colon, ::Colon, ::Colon)
