Hi Andrea - Make sure that the b-value table and gradient table are saved as plain text files. When you run the "more" command on them, you should see all the numbers and only numbers.
This is what I get when I run more on your files (this may vary depending on the flavor of unix you have on your computer):
% more bvals.txt 0^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000 ^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M1000^M^M1000^M1000^M1000^M1000^M1000^M1000 % more bvecs.txt "bvecs.txt" may be a binary file. See it anyway? ??0^@ ^@0^@ ^@0^@^M^@ ^@-^@1^@ ^@0^@ ^@0^@^M^@ ^@0^@ ^@-^@1^@ ^@0^@^M^@ ^@0^@ ^@0^@ ^@1^@^M^@ ^@0^@.^@0^@4^@2^@ ^@0^@.^@1^@1^@5^@ ^@-^@0^@.^@9^@9^@3^@^M^@ ^@-^@0^@.^@1^@7^@5^@ ^@0^@.^@2^@ ^@-^@0^@.^@9^@6^@4^@^M^@ ^@-^@0^@.^@2^@3^@2^@ ^@0^@.^@1^@6^@3^@ ^@-^@0^@.^@9^@5^@9^@^M^@ ^@-^@0^@.^@3^@6^@8^@ ^@-^@0^@.^@0^@2^@6^@ ^@-^@0^@.^@9^@3^@^M^@ ^@-^@0^@.^@1^@9^@ ^@-^@0^@.^@3^@7^@4^@ ^@-^@0^@.^@9^@0^@8^@^M^@ ^@0^@.^@1^@1^@7^@ ^@-^@0^@.^@8^@3^@3^@ ^@-^@0^@.^@5^@4^@^M^@ ^@0^@.^@2^@ ^@-^@0^@.^@2^@5^@3^@ ^@-^@0^@.^@9^@4^@7^@^M^@ ^@0^@.^@4^@9^@6^@ ^@-^@0^@.^@1^@3^@4^@ ^@-^@0^@.^@8^@5^@8^@^M^@ ^@0^@.^@0^@1^@4^@ ^@0^@.^@6^@2^@8^@ ^@-^@0^@.^@7^@7^@8^@^M^@ ^@0^@.^@7^@4^@4^@ ^@0^@.^@1^@4^@8^@ ^@-^@0^@.^@6^@5^@1^@^M^@ ^@0^@.^@7^@6^@1^@ ^@-^@0^@.^@3^@2^@ ^@-^@0^@.^@5^@6^@4^@^M^@ ^@0^@.^@1^@8^@1^@ ^@-^@0^@.^@9^@2^@5^@ ^@-^@0^@.^@3^@3^@5^@^M^@ ^@0^@.^@6^@8^@ ^@0^@.^@4^@2^@2^@ ^@-^@0^@.^@6^@^M^@ ^@-^@0^@.^@7^@7^@7^@ ^@-^@0^@.^@4^@7^@1^@ ^@-^@0^@.^@4^@1^@8^@^M^@ ^@-^@0^@.^@9^@2^@4^@ ^@0^@.^@1^@0^@4^@ ^@-^@0^@.^@3^@6^@8^@^M^@ ^@-^@0^@.^@4^@6^@8^@ ^@0^@.^@7^@6^@7^@ ^@-^@0^@.^@4^@3^@8^@^M^@ ^@-^@0^@.^@8^@8^@2^@ ^@0^@.^@1^@8^@9^@ ^@-^@0^@.^@4^@3^@2^@^M^@ ^@-^@0^@.^@6^@9^@ ^@-^@0^@.^@7^@0^@6^@ ^@-^@0^@.^@1^@5^@7^@^M^@ ^@-^@0^@.^@2^@3^@9^@ ^@-^@0^@.^@7^@5^@7^@ ^@-^@0^@.^@6^@0^@8^@^M^@ ^@0^@.^@0^@5^@8^@ ^@-^@0^@.^@9^@8^@4^@ ^@0^@.^@1^@7^@^M^@ ^@0^@.^@5^@3^@7^@ ^@-^@0^@.^@8^@3^@6^@ ^@-^@0^@.^@1^@1^@3^@^M^@ ^@0^@.^@9^@9^@2^@ ^@0^@.^@1^@2^@1^@ ^@-^@0^@.^@0^@4^@2^@^M^@ ^@0^@.^@9^@9^@7^@ ^@-^@0^@.^@0^@7^@1^@ ^@-^@0^@.^@0^@3^@8^@^M^@ ^@0^@.^@8^@7^@2^@ ^@-^@0^@.^@4^@7^@8^@ ^@-^@0^@.^@1^@0^@1^@^M^@ ^@0^@.^@2^@4^@9^@ ^@-^@0^@.^@9^@3^@3^@ ^@0^@.^@2^@5^@8^@^M^@ ^@-^@0^@.^@1^@1^@8^@ ^@-^@0^@.^@9^@9^@2^@ ^@-^@0^@.^@0^@4^@7^@^M^@ ^@-^@0^@.^@3^@3^@8^@ ^@-^@0^@.^@8^@4^@1^@ ^@0^@.^@4^@2^@2^@^M^@ ^@-^@0^@.^@5^@2^@9^@ ^@-^@0^@.^@8^@4^@1^@ ^@0^@.^@1^@1^@6^@^M^@ ^@-^@0^@.^@9^@9^@7^@ ^@-^@0^@.^@0^@5^@5^@ ^@-^@0^@.^@0^@5^@7^@ On Fri, 4 Sep 2015, andrea cristina Lima wrote:
Please I am having the problem: bvecs and bvals don't have the same number of entries I tried to use the bvecs and bvals files as suggested in the Tutorial, but doesn't work. Please see the files attached (log, files and script). Thank you very much -- Andrea Cristina de Lima PardiniCV: http://lattes.cnpq.br/0921194840474573
