Change path in data.py to fix travis CI fail

[BenjaminHsieh]

Check to see if travis ci passes

[changsiyao]

Maybe need to import os first

[BenjaminHsieh]

do you mean in the data file?

[BenjaminHsieh]

ok finally go it to work, the coverage will decrease because the hashList is being loaded from the call to main, which is ignored by travis ci. Anyway, this should work for everyone, someone can merge and test it out

Can also close #14

Wait, I'm having problem with this file. If I change directory to the folder above, then the path for all the files are wrong.
Traceback (most recent call last):
File "data.py", line 42, in
check_hashes(d)
File "data.py", line 26, in check_hashes
digest = generate_file_md5(k)
File "data.py", line 13, in generate_file_md5
with open(filename, "rb") as f:
IOError: [Errno 2] No such file or directory: u'ds005/sub015/BOLD/task001_run001/QA/DVARS.png'

I got this. I think we need to change the directory back after loading the hashList, like:
if name == "main":
os.chdir('..')
with open('data/hashList.txt', 'r') as hl:
d = json.load(hl)
os.chdir('data/')
check_hashes(d)

[BenjaminHsieh]

hmmm, weird, I have the opposite, if I add oc.chdir('data/') before check_hashes(d), then I get that same error

[changsiyao]

Other people should check, otherwise, let's ask tmr in office hours.

@changsiyao try this, I have this that works:

if name == "main":
with open('hashList.txt', 'r') as hl:
d = json.load(hl)
check_hashes(d)

[BenjaminHsieh]

this assumes that you have the ds005/ in data directory

[changsiyao]

This (without all the changing directory steps) works for me, but I thought this wouldn't pass the test?

[BenjaminHsieh]

lol it passed just now

[BenjaminHsieh]

lets get someone else to check just in case and if its good we can merge it

[changsiyao]

eh...... But I suppose it's a good thing, lol~

[BenjaminHsieh]

can someone test this and merge it thanks, it will probably allow us to pass the failure in #31 @boyinggong @BrianQIu @pigriver123
