I just ran your code with your dataset but I get this type error and unable to figure it out. Kindly help me resolving this error

Hello @czainab, can you kindly mail me the dataset too?

[mrinal18]

if you are running it in python3, then filter doesnt return list but an iterable filter object.

So use list before filter and it should work
first_p = list(mean_array).index(list(filter(lambda x: x>0, mean_array)[0]))

[czainab]

Well I downloaded the images in test, train text file from ADNI website. You can just simply apply for the access.
Thank you for your help but I tried the above solution and it didn't work for me now I am getting another error in the same file on slice_p = int(round(first_p + (last_p - first_p)*fraction)) and the error is TypeError: unsupported operand type(s) for -: 'tuple' and 'tuple'
Kindly help me out

[czainab]

Can you please guide me how you were able to run this file because I am like getting errors on every line. I just fix one error and got another on the very next line.

[mrinal18]

look at #1, where he explained how to run the code. Kindly tell me if it runs

[czainab]

Still getting the same error TypeError: 'filter' object is not subscriptable.

[mrinal18]

I noticed you are running this using anaconda3 which as python 3+.

kindly try running this using python2.

[mrinal18]

Hey, so i took the access of the ADNI data, can you kindly guide me what to do after that? i cant seem to find the data.

[czainab]

After login go to Projects, than ADNI, than click on Download, Image Collection and under Data Collection tab you will find the images.

@czainab , replace it with this

first_p = list(mean_array).index(list(filter(lambda x: x>0, mean_array))[0])

@czainab , replace it with this

first_p = list(mean_array).index(list(filter(lambda x: x>0, mean_array))[0])

Did this code worked . Please let me know
thank yoy
