- Add detailed error messages to integrity check function
- Fix silent failure case where save loop could exit without success
- Return specific error reasons (file missing, empty, corrupt, etc.)
- Add final success check with explicit error if all attempts fail
- Improve warning messages with specific failure reasons

This should help diagnose why MAT files aren't being written after averaging.

Addresses critical HDF5/MAT file corruption issues during copy operations by:

**Enhanced Atomic Save Operations:**
- Add post-move integrity verification to catch filesystem corruption
- Implement additional sync and pause before move operations
- Add move operation success checking with detailed error reporting
- Handle rare post-move corruption scenarios with file cleanup

**New Safe Copy Utility (BH_safeCopyMatFile):**
- Multi-strategy copying: load-and-save, filesystem copy, rsync with checksum
- Comprehensive integrity verification at each step
- Automatic fallback between methods if one fails
- Handles HDF5 sparse file corruption issues with Unix cp command
- Creates backups before overwriting existing files

**Technical Solutions for Known Issues:**
- Addresses HDF5 sparse file corruption during cp operations
- Implements filesystem cache flushing and sync barriers
- Uses atomic rename operations instead of copy when possible
- Provides rsync with checksum verification for Unix systems

This resolves the specific issue where MAT files become corrupt after
copying with Unix cp command, even when the original file loads correctly.

Added extensive debug output to track every step of the save operation:

**Save Operation Debugging:**
- Input data validation (class, field count, currentCycle)
- Disk space information before save attempts
- Detailed timing for each operation (save, sync, integrity check, move)
- Temp file creation and size verification
- Move operation success/failure with detailed error messages
- Exception catching with full stack traces and identifiers

**Integrity Check Debugging:**
- File existence and size validation
- Variable information extraction with timing
- Variable name listing and subTomoMeta detection
- Variable metadata (size, class, bytes)
- Structure loading with timing
- Field enumeration and key field verification
- Detailed error classification (HDF5/compression vs general)

This should provide complete visibility into exactly where and why
the atomic save operations are failing during averaging.

This commit resolves the critical "MATLAB:load:numColumnsNotSame" corruption
issue by fundamentally changing how metadata is passed between BH_average3d
and BH_fscGold_class.

Key changes:
- Refactor BH_fscGold_class to accept parameters directly instead of loading
  full metadata from disk, eliminating problematic disk I/O operations
- Update BH_average3d to pass minimal data to fscGold and update in-memory
  subTomoMeta directly, removing the corruption-prone reload operation
- Remove masterTM struct entirely from fscGold, working directly with
  passed parameters and returning only modifications
- Clean up debug print statements from both functions

This architectural change eliminates the root cause of corruption while
maintaining all scientific functionality. Testing confirmed that the
refactored version completely eliminates the corruption issue.

Fixed critical bug where particles were lost during tilt series processing:

**Root Cause:**
- n_included_this_prj was reset per projection, only counting last projection
- Tilt series with particles in early projections but empty final projection
  would discard entire tilt series stack despite particles in memory

**Key Changes:**
- Replace per-projection counter with n_particles_this_tilt_series
- Track particles across ALL projections in each tilt series
- Add comprehensive debug output for validation and troubleshooting
- Remove skip_to_end and multi-node logic (moved to external programs)
- Add error handling for particle stack assignment failures
- Clean up unused variables and verbose output

**Validation Fix:**
- particles_stack_added now equals total_particles_in_stack
- Stack slices match star file records exactly
- Comprehensive debug shows particle flow through entire pipeline

All 35,458 particles now properly saved to both stack and star files.

- Function now runs without undefined variable errors
- Core validation logic preserved and functional

… parsing

- Fix file format detection issue where .tmp files were interpreted as ASCII instead of binary MAT files
- Change temp file extension from .tmp to .tmp.mat for proper format recognition
- Prioritize v7 format over v7.3 for better immediate load compatibility
- Add robust retry logic with delays for v7.3 (HDF5) format files
- Implement multiple sync attempts for HDF5 files to ensure data is fully flushed
- Fix mask command to not require parameter file (add to multiGPUs=0 list)
- Fix mask command argument count check (was expecting 5, now correctly expects 4 for shape-based masking)

The main issue was that MATLAB's load() function was misidentifying .tmp files as ASCII text files
instead of binary MAT files, causing "Unknown text on line number 1" errors. Using .tmp.mat extension
ensures proper format detection.

- Switch from TILT (Y-axis only) to SPIDER (ZYZ) rotation convention
- Add Y-padding calculation to account for in-plane rotation during chunking
- Update coordinate transformations to use full 3x3 rotation matrix
- Store 2D rotation matrix (A11, A12, A21, A22) in TLT columns 7-10
- Update EMC_setup_synthetic_project to read rotation matrix from TLT for .xf file
- Add clarifying comments to BH_defineMatrix about rotation conventions

The rotation matrix stored is the inverse of the applied rotation, following
IMOD convention where .xf describes how to align raw projections.

Add wrapper interface for simulation functions:
- emClarity simulate tomogram    - Generate synthetic 3D tomogram
- emClarity simulate tlt_file    - Generate synthetic tilt geometry file
- emClarity simulate projections - Generate tilt series from tomogram
- emClarity simulate project     - Set up complete emClarity project

Template input supports single MRC or text file with MRC/PDB pairs
(alternating lines: odd=MRC, even=PDB/CIF).

KNOWN ISSUE: There are inconsistencies in the transformed output
suggesting a misalignment with IMOD conventions. The coordinate
transforms and rotation matrices may not match IMOD's expected
handedness or origin conventions.

TODO: Add debug mode for precise coordinate validation:
- Generate tomogram with well-defined cross-hair densities at known
  positions for sub-pixel precision coordinate verification
- Option to skip Poisson noise draw for cleaner signal
- Option to skip CTF application for simpler debugging
- Compare reconstructed particle positions against ground truth CSV
  to isolate where convention mismatches occur

  file (_cisTEMOriginalXPosition), add optional tile size override via
  cisTEM_output_tile_size parameter.

- Register 'ctf ctfRefine' subcommand in testScripts/emClarity.m

- Add cisTEM_output_tile_size parameter to BH_parseParameterFile.m
