Dear all,

I am trying to load preprocessed HCP data (rfMRI_REST1_LR_hp2000_clean.nii) into CONN to develop a surface-based analysis pipeline. I have two questions:

1) when loading the file with 1200 volumes (rfMRI_REST1_LR_hp2000_clean.nii) I get this error. Differenlty, I can load the same unprocessed data without problems.

ERROR DESCRIPTION:
 
Error using spm_sample_vol
File too small.

Error in conn_fileutils (line 454)
 else [varargout{1:nargout}]=spm_sample_vol(V,varargin{2:end});

Error in conn_menu>conn_menu_selectslice (line 1280)
 case 3, y=[]; for nv=1:numel(x.vol), ty=reshape(conn_fileutils('spm_sample_vol',x.vol(nv),reshape(x.x(:,:,n),1,[]),reshape(x.y(:,:,n),1,[]),reshape(x.z(:,:,n),1,[]),1),x.dim([1 2])); y=cat(4,y,ty(end:-1:1,end:-1:1)'); end

Error in conn_menu (line 924)
 title=conn_menu_selectslice(data.x1,data.n,data.view); 

Error in conn (line 2754)
 conn_menu('updateimage',CONN_h.menus.m_setup_00{5},cfile{3});

Error in conn_filesearchtool (line 168)
 if length(h.callback)>1, feval(h.callback{1},h.callback{2:end},names); else, feval(h.callback{1},names); end

SUGGESTIONS:
 
Potential corrupt or incomplete volume. Try revising or regenerating source volumes

2) After solving this problem, do you have any suggestions on pre-processing and denoising data for surface analysis with preprocessed HCP data?

any comments or suggestions are greatly appreciated

Best
