输入参数不够.程序要求输入参数有p,n,m,t,你就给个line 4当然不对.
也就是说p，n，m，t必须有值？
是的。另外你程序第二行的没必要写，这三个是传入变量，你传进去是什么类型的就是什么类型了。
n,m,t要求取整怎么办？
n,m,t要求取整那你传进去的n,m,t值就要是整形咯。

What were you expecting? Your 5th field specifier in the format is %5f which
is a format for a floating point number, but your fifth field is
'Left-Lateral-Ventricle' which is definitely not a floating point number.
Were you expecting the initial %*s to somehow read from the beginning of the
line to the end of the 'Left-Lateral-Ventricle' string?

I was expecting the initial %*s to skip the space at the beginning of each line. If I remove the %*s then the error changes to the 6th field, rather than the 5th. I'm new to matlab and not really sure which formats to use.

I was expecting the 6th field to be the 'Left-Lateral-Ventricle' string and the %*s to skip the space, which occupies the first column of data. I'm fairly new to matlab, so am not sure if this is correct or not.
When I remove the %*s, then the error changes from the 5th field to the 6th field.

The %s format skips leading whitespace _before_ it begins to read characters,
so with the %*s in there, the first two blanks on the line would be skipped as
whitespace and then the '1' or '2' etc would be recognized as a string.
The %2d would start after that without having read all of the second column of
numbers... and problems cascade from there. The %5f after that would read all
As you do not appear to have any fields that run together, I suggest you use
'%d%f%f%f%s%f%f%f%f%f'
In this case, where there are no widths on the formats, leading whitespace
will automatically be skipped before reading each numeric format.

textscan does not read into scientific format, but your display format might
be set to show in scientific format. Try commanding
